Summary:
Editor changes caret visibility during drag and drop. But when destroying
editor, we don't restore caret state. So we should restore it when destroying
editor.

This makes our behavior a bit closer to Blink / WebKit.
This patch fixes multiple issues:
First, fixes the caret movement getting stuck on a <select> element inside an
editor. This is because of the IsRootOfAnonymousSubtree() check that I'm
removing. Instead of that, consider NAC unselectable in UsedUserSelect, just
like generated content. This makes us jump across it correctly, and doesn't
regress the test-case that was added in bug 989012.
Second, it allows to select nodes with user-select: none as long as you're on an
editor. This matches WebKit and Blink. It's something you could do earlier
regardless with user-select: all on the parent, which is why the reporter's
test-case worked before my patch. I think being able to jump across these and
delete them on an editor is the right thing to do.
It adds tests for all this plus the same thing working for non-editable contents
(there was no pre-existing test for that).

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

The elements under <body> are treat as content append, so their frames
will be construct by nsCSSFrameConstructor::ContentAppended.
This patch fixed only the simple "append" case which is appending to the
last continuation of ::moz-column-content. For other more complex
appending or inserting cases, we might need to reframe (bug 1504053).

If there is no scrollable frame, PresShell::GetScrollableFrameToScroll() returns
nullptr. However, even when we don't expand selection, we need to move caret
in current selection root. Therefore, it should call
nsFrameSelection::CommonPageMove() with the result of
nsFrameSelection::GetFrameToPageSelect() to move caret.

This converts the tabmodalprompt binding to a class, to be constructed along side with the element
by TabModalPromptBox.
TabModalPromptBox will keep the instances in a map and pass it to the callers, instead of the element.

nsFrameSelection::CommonPageMove() is called only by
nsTextInputSelectionImpl::PageMove() and PresShell::PageMove(). So, this is
the only implementation of (Shift+) PageDown and (Shift+) PageUp.
This scrolls down/up the specific frame. However, this allows to scroll
outside of selection limiter, for example, even when an editing host is
focused, its parent scrollable element may be scrolled. This is same behavior
as Blink so that we should keep this behavior.
However, it also emulates to click same position after scroll and this behavior
is different from Blink. At this time, it does not check selection limiter and
then, nsFrameSelection::HandleClick() may reset selection limiter the scrolled
frame is a parent frame of the limiter.
Therefore, this patch makes it check if the scrolled frame is a parent of the
limiter, and if so, use result of GetFrameToPageSelect() to emulate a click
instead. The result won't be a parent of the limiter because it is used when
handling Shift + PageDown and Shift + PageUp which are always handled in the
limiter.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>
If you start moving to the left from the second line, for example.
I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file
follow-ups for those.

test_expanding_selection_per_page.html creates another window and requires
focus event on each case which creates editing host because
EditorEventListener::Focus() sets ancestor limit of Selection as the editing
host. Therefore, if the window itself does not have focus, focus event won't
be fired on editing hosts. So, the reason why the orange occurs almost all
with opt build is, debug build is enough slow to wait focus of new window
before running test.

PresShell::PageMove() climbs up to parent document when there is no scrollable
parent in current document. However, if aExtend is true, it should expand
Selection in the document itself. Therefore, it needs different rules to
look for container of expanding Selection from scrollable element to scroll.
Additionally, old rules (i.e., before the fix of bug 1369072 which caused
this regression) were also buggy. It used parent scrollable element or
root scrollable element simply. Therefore, if found scrollable element is
ancestor of selection limiter, it didn't work as expected.
This patch creates nsFrameSelection::GetFrameToPageSelect() to retrieve
per-page selection container element with the following rules:
- look for a scrollable element in selection limiter.
- if there is no scrollable element, use selection limiter.
- if there is no selection limiter, use the root frame.
So, nsFrameSelection::CommonPageMove() should take nsIFrame rather than
nsIScrollableFrame since container of per-page selection may be used in
non-scrollable contenteditable element. If it's called with non-scrollable
frame, it needs to compute the expanding range with the frame size.

Summary:
The behavior the WG proposed is way more subtle than what that bug implements,
including:
* Implementing two logical overflow longhands.
* Expanding the overflow shorthand to different longhands depending on the
syntax of that.
Meanwhile, Blink hasn't done the swap and will ship the same behavior that we
shipped in Firefox 61 (bug 1453148), that is, overflow-x, then overflow-y.
So I think lacking a clear way forward we should revert this change and preserve
our shipped behavior.
