As far as I can tell, the intermittent suite_start failures are due to
stdout/stderr output interleaving -- a known issue for reftest logging,
without a clear way forward. Let's work around it the same way we did
on Windows.

Inheriting block-size is just plain wrong in presence of calc or percentages.
The layout without these rules also matches other browsers, so I see no reason
not to do this.

As described in https://bugzilla.mozilla.org/show_bug.cgi?id=1562122#c5,
this precomputed argument is not our children's block-size, but is the
block-end edge of children because aState.mBCoord is initialized as our
border-padding block-start in BlockReflowInput's constructor.
I also delete the sentence "The final block-size that is used in
aMetrics will be set ..." because this is the implementation details of
this function, and is likely to become inaccurate after considering the
block split by column-span.

Because aStatus is also used as an output argument, caching aStatus as
our children's reflow status can and make the logic that morphs aStatus
to our reflow status easier to follow. And this helps the patch I'm
going to add for computing the block-size for column-span split.

We usually use reference to manipulate nsReflowStatus like in Reflow().
The documentation for aStatus needs edit, and is done in next part.

ComputeFinalBSize() doesn't need to modify the final inline-size, so we
don't need to pass the entire LogicalSize into it.
Also, aReflowInput.AvailableBSize() is used multiple times. Cache it to
shorten some statements.

And remove some of the ::placeholder and ::cue hacks where we need to use
!important to make the property not apply for content but apply on UA sheets.
The comment about the white-space property was wrong, we don't enforce it with
!important in the UA stylesheets for <input> (we do for <textarea> though), so
I've kept the flag since it really applies.

Looks like some users use it, and it's not too much effort to support. This is
somewhat simpler, and IMO better than what existed before bug 1514655 because:
* It doesn't regress bidi rendering when the pref is disabled (before, the pref
would prevent plaintext.css from applying altogether).
* It's consistent with the way view-source docs work.
* It doesn't use non-standard stylesheet APIs to toggle the stylesheet
(bug 1260720).

We don't need to treat a details frame as if it has multiple content
insertion points in order to reframe it. We can just put the logic into
WipeContainingBlock().
The reftests layout/reftests/details-summary/dynamic-add-*.html also
cover adding <summary> into a <details> in various situations.

According to this resolved spec issue:
https://github.com/w3c/csswg-drafts/issues/2140,
we retire the 3-valued <position> on
1. `object-position`
2. `perspective-origin`,
3. `mask-position`
4. `circle()` and `ellipse()`
, but still keep the support for `background-position`.
Besides, I simply run this python script to generate the .ini file:
```
s = sys.argv[1] + ".ini"
with open(s, "w") as f:
f.write('[{}]\n'.format(sys.argv[1]))
f.write(' expected: FAIL\n')
f.write(' bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1559276\n')

Update the existing reftests to not use 3 valued syntax.
I run the script to update the syntax in
`layout/reftests/w3c-css/submitted/images3/*`,
`layout/reftests/w3c-css/submitted/masking/*`,
`layout/reftests/xul/*`, and
`layout/reftests/webm-video/*`:
```
function rename() {
find layout/reftests/\
-type f\
! -path "./obj*"\
! -path "./.git"\
! -path "./.hg"\
\( -name "*.html" -or\
-name "*.xul" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
rename "object-position: top 3px center" "object-position: top 3px left 50%"
rename "object-position: center right 25%" "object-position: top 50% right 25%"
```
For `layout/reftests/svg/svg-integration/clip-path/*`, I just manually
update them.

This will have two benefits:
1) Align test setup with shipping Firefox - We don't allow content
privilege XUL in shipping versions of Firefox, so having the tests be
chrome would be more realistic to our use case.
2) Support the XUL to XHTML migration. These files will soon become XHTML
files, but will still need to load XUL elements, so they'll need to be
marked as chrome privileged to continue working.
One test (404149-1.xul) is now disabled, since it fails when loaded as
chrome. Bug 1557383 was filed to address this.

It wasn't working because it was testing inline size == NS_UNCONSTRAINEDSIZE
rather than block size, so it was taking always the reflow path.
The attached test is on par with the vertical-lr / horizontal-tb cases with
this patch, but takes way over 10s without it.

This is a weird pref.
First, it is VarCached into two different global variables, one in
nsSubDocumentFrame.cpp, and the other in nsView.cpp.
Second, the pref is not defined by default. When the VarCache variables are
initialized they are therefore set to the default value provided to the
`AddBoolVarCache()` call, which in both cases is `true`. This semantics isn't
possible with `StaticPrefs`, so the patch defines the pref as true by default.

across the cross-origin document boundaries, which is bug 1561754. So once
after we make 'Find in page' work in fission world (bug 1553384), we should

browserElement_ScrollEvent.js is affected by this change. Before this change
the document for iframe mozbrowser was not considered as the root content
document, but after this change, it's considered as the root content document.
Given the nature of iframe mozbrowser, I believe it's the right behavior.
The browser mochitest in this commit fails without this change since
the minimum-scale size is used in the out-of-process iframe so that the visual
viewport size gets 3x bigger than the expected size.
