Summary:
FlushTarget wants to decide whether we should flush the parent document or all
of them. However, the only point of flushing parent documents is that media
query changes could affect the document we really want to flush.
That's completely pointless if we actually don't flush the subdocument, so just
skip doing that. This case is already checked (see the DocumentNeedsRestyle
stuff, which is also somewhat poorly named, which walks up the document chain).

Now that what we use to decide whether a document is styled by Servo are only
prefs and the doc principal, we don't need to inherit the style backend type,
since unless the pref has changed, the result will be the same.

To avoid unpleasant FOUCs, defer autofocus processing until frames are
constructed in PresShell::Initialize.
Resolve the race between nsAutoFocusEvent running and page load by checking the

Everything that needs them up-to-date will call flush appropriately, there
should be no need to do it manually.
This way we coalesce all the stylist updates until the next style flush in the
best case, or until one of the consumers actually needs them.

In contrast to nsIDocument::EnumerateSubDocuments(), this new function is
supposed to work with the callback function which does not mutate any state
in the document, and also this function checks all descendant documents even
if there is a descendant that the callback function returns false.

This is a short-term solution to our inability to apply CSP to
chrome-privileged documents.
Ideally, we should be preventing all inline script execution in
chrome-privileged documents, since the reprecussions of XSS in chrome
documents are much worse than in content documents. Unfortunately, that's not
possible in the near term because a) we don't support CSP in system principal
documents at all, and b) we rely heavily on inline JS in our static XUL.
This stop-gap solution at least prevents some of the most common vectors of
XSS attack, by automatically sanitizing any HTML fragment created for a
chrome-privileged document.

This makes the pres shell be notified as the last observer unconditionally.
In practice this doesn't matter, and it may already be the case if an iframe
goes display: none and back. In practice, the only dependency that requires this
order is that the pres shell needs to be notified _after_ the content sink, so
we don't try to enter frame construction before beginning the shell update.
That may be worth looking into, but definitely not in the scope of this bug... :)

This also removes some confusing comments around nsIDocument regarding some kind
of "special" stylesheets, which don't seem to exist anymore, and consolidates
StyleSheetList so that we only have one implementation.
I think that fixes a potential leak on the shadow root code (even though the API
is v0 only), given the pointer from the ShadowRootStyleSheetList to the
ShadowRoot wasn't being CCd.
Also, more stuff could be renamed, methods removed, etc, feel free to suggest
more cleanup, I've done mostly the minimal.
Next steps are moving the stylesets there and stop using the proto binding sheet
list / resources.

See bug 1422633, there are assertions missing, and servo doesn't assert at all
anymore.
I don't think it's worth optimizing / lazily resolving it, each time the
document state changes.
We usually just restyle the world anyway (which requires recomputing it), and
the changes that it's optimizing (nsWindow::SetActive() and XUL root element
localedir attribute changes) aren't common enough to warrant the complexity I'd
say.
This doesn't handle invalidating the cache in the case the root element goes
away, I haven't bothered because it was already broken, and GetRootElement() is
already gone in RemoveSubtreeFromDocument.

This is to fix the case where preference is restore to false when a testcase
ends, but nsDocument::DeleteShell is called afterwards. So, we make the
preference per-doc and set it when the document is created. The value does not
change for the lifetime of the document.
This is to fix the case where preference is restore to false when a
testcas ends, but nsDocument::DeleteShell is called afterwards. So, we
make the preference per-doc and once it is enabled for a document, it
stays enabled.
There's nothing preventing the flat tree from changing while the document
doesn't have a shell. In that case, we really really don't want to lose track
of elements with stale style data, since then we'll mess up.
It's ok to _not_ clear the style data when the document goes into the BFCache
though, because the document is thrown away if other document runs script and
touches the cached DOM.

Add a new member mAllowPaymentRequest on nsIDocument and following related
methods,
bool AllowPaymentRequest() const
void SetAllowPaymentRequest(bool aAllowPaymentRequest)
mAllowPaymentRequest is used to check if PaymentRequest is allowed to use on
the document. According to the spec
https://html.spec.whatwg.org/multipage/iframe-embed-object.html#allowed-to-use
the mAllowPaymentRequest should be true under following situations
1. The document is the top level content document.
2. The document is the same origin with its parent document and its parent
document's mAllowPaymentRequest is true.
3. The document is different origin with its parent document but its
parent node is an iframe with allowpaymentrequest flag and the parent
document's mAllowPaymentRquest is true.
This patch also include following mochitests
1. test for allowpaymentrequest flag changing. The flag change effect should
not be applied to the document immediately, it should be updated while
the browsing context is updated.
2. test for effect propagation in the nested iframe.
Per spec, document objects have a throw-on-dynamic-markup-insertion counter,
which is used in conjunction with the create an element for the token algorithm
to prevent custom element constructors from being able to use document.open(),
document.close(), and document.write() when they are invoked by the parser.

Since the presence of an entry with a null selector is different for Gecko and
Servo, this seemed easier, and mimics nsLayoutStyleSheetCache.

Right now every document in a docshell makes a copy of the list. In practice,
this list is usually pretty short (limited by depth of iframe nesting), so this
is probably not a problem. We could add a bit of complexity and have a
refcounted struct that contains the list... I wish we had something as simple
as Rust's Arc that we could use here.

Per mixed-content-blocked spec, [1], <img srcset> and <picture> should
be blocked. However we still fetch <img srcset> and <picture> in image
preload, because they are fetched with contentPolicyType
TYPE_INTERNAL_IMAGE_PRELOAD and won't be rejected by nsMixedContentBlocker.cpp.
So I updated the image preloading code, and use the type TYPE_IMAGESET
if the image request is for <picture> or <img srcset>, otherwise for
normal image load we still use TYPE_INTERNAL_IMAGE_PRELOAD.
[1]: https://w3c.github.io/webappsec-mixed-content/#should-block-fetch
4. Return allowed if one or more of the following conditions are met:
request’s type is "image", and initiator is not "imageset".
5. Return blocked.
We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

nsTextFrame stores text as single byte character array if all characters are
less than U+0100. Although, this saves footprint, but retrieving and modifying
text needs converting cost. Therefore, if it's created for a text node in

Our current machinery for enabling stylo requires a docshell - if there isn't
one, we default to the Gecko style system.
When getComputedStyle operates on an element without a presshell, it uses the
caller's presshell instead. If the element has previously been styled with
one style system (but no longer has a presshell), and the caller uses a
different style backend, using the caller's style system can cause crashes when
we pull bits of cached data off the DOM (like cached style attributes).
So we want to throw when window.getComputedStyle(element) is called for a
(window, element) pair with different style backends (which is what the next
patch in this bug does).
However, that causes a few failures where stylo-backed documents try to do
getComputedStyle on an XHR document (which, without a docshell, will use the
gecko style system).
So this patch does some work to propagate the creator's style backend into
various docshell-less documents. This should allow both chrome (which uses gecko)
and content (which uses stylo) to use getComputedStyle on the response document
for XHRs they create.
Note that the second patch in this bug will make
chromeWin.getComputedStyle(contentObj) throw. If we discover code that does
that, we can just make it invoke the content's getComputedStyle method over Xrays.

This commit changes async keyboard scrolling to be enabled only if the content to
scroll is from a selection. This works around the problem of detecting whether
an arbitrary element has key listeners that should prevent async key scrolling,

The <content> in an XBL document could be injected into documents with
different style backend types. Therefore, we need to set the XBL document's
style backend to the same as the bound document's so that the style
attribute of the content can be processed by the correct backend. <marquee>
elements in xbl-marquee.xml is one such example.
