Known issues:
* Display list optimization can sometimes optimize out elements that
should be shown. This affects the Enyo demo.
* The `overflow: scroll` container doesn't clip the inner layer properly
when borders, border radius, etc. are present.
* `overflow-x: scroll` and `overflow-y: scroll` don't work individually;
elements are scrolled all at once.
* Scrolling only works on absolutely-positioned elements.
At this point the only thing it does is to try to avoid adding display
items that are outside the root scrollable area, which is both wrong
(since it's incompatible with having scrollable areas outside the root)
and is useless (because we have displayports now).
at the last known good split point, and use it for `white-space:
nowrap`.
Fixes overflowing tables on Wikipedia.
This infrastructure should form the basis of our fix for inline layout
of fragments that don't themselves constitute valid split points. That
will require some more work, however.
The failing `float-applies-to-*` CSS 2.1 tests never really should have
been passing in the first place; they depend on floats inside
fixed-layout tables working properly, which they don't.
Closes#6078.
Closes#6709.
Closes#6858.
layout: Take inline margins into account when determining the intrinsic sizes of fragments.

Use Box<str> instead of Box<String> for UnscannedTextFragmentInfo
This removes an extraneous layer of indirection, without increasing the size of the `SpecificFragmentInfo` enum (because `Box<str>` is a fat pointer, which is the same size as the `FlowRef` trait object that is already stored in `InlineAbsoluteHypotheticalFragmentInfo`)

Fixes lots more jumpiness.
A manual test, `inline-pseudo-repair-jumpiness.html`, has been added. I
was unable to automate it, so I will file a followup issue on that.

Fixes jumpiness on many pages; e.g. the WPT results pages.
For some reason, this would not reproduce with an automated test.

It's not possible to correctly determine during the css cascade whether the container height
is explicitly specified. Additionally, the spec https://drafts.csswg.org/css2/visudet.html#the-height-property
says this should affect the *used* height, rather than the computed height.
This significantly improves the layout in #6643.
new styles are set.
Tying transitions to the DOM node avoids quadratic complexity when
updating them.
Finishing transitions instantly when styles are updated makes our
behavior more correct.
