layout: Only take nonnegative margins into account when estimating inline placement of floats.
Otherwise, the heuristics can pass even when there are no floats,
causing block formatting contexts to be speculated to be flowing around
floats that don't exist!
Closes#10237.

Restore stripped whitespace before reflowing text fragments
Fixes#10200. r? @pcwalton
Note: The reftest uses a transition of non-zero duration, because I couldn't find any other way to reproduce the bug. Unfortunately this makes it unreliable in debug builds. I tried to fix this using reftest-wait with setTimeout and requestAnimationFrame, but it still wouldn't complete the animation consistently. To make the test work in debug builds we may need `transitionend` events (#10245) or a different way to reproduce the bug.

Allow setting preferences to false in WPT tests
First patch to servo - apologies if I did something stupid :)
This is a fix for #10161. I have squashed the commits into one.

Highlight selected text in input fields
Fixes#9993. This does not yet allow stylesheets to set the selection colors; instead it uses a hard-coded orange background and white foreground.

speculation code.
The old code tried to do the speculation as a single bottom-up pass
after intrinsic inline-size calculation, which was unable to handle
cases like this:
<div>
<div style="float: left">Foo</div>
</div>
<div>
<div style="overflow: hidden">Bar</div>
</div>
No single bottom-up pass could possibly handle this case, because the
inline-size of the float flowing out of the "Foo" block could never make
it down to the "Bar" block, where it is needed for speculation.
On the pages I tried, this regresses layout performance by 1%-2%.
I first noticed this breaking some pages, like the Google SERPs, several
months ago.
Fixes for compute_damage
A few changes:
* Make `compute_damage` short-circuit more, by skipping comparisons if they will only set flags that are already set.
* Update some obsolete comments.
* Add a bunch of missing properties to `compute_damage`.
* Set `RECONSTRUCT_FLOW` when `text-decoration` changes, because it can affect text fragment splitting/merging.
I believe this is all of the computed properties except for the animation properties. (I wasn't sure what to do with those.) After this lands I'd like to work on moving this information into `properties.mako.rs` so that this function can be auto-generated, and so that newly-added properties can default to setting all flags instead of none.

Details ui
Requires a patch to rust-selectors, and doesn't currently recalculate the styles correctly (which is needed to make actual toggling work correctly).
Still trying to figure out what it takes to get style recalc to do what this needs.

Refactor the cascade
Converting the specified value of some properties into a computed value depends on the value of other properties. For example, the `em` unit of any length depends on the `font-size` property.
Previously, we would do a first pass over applicable declarations to build up a `values::computed::Context` struct with a number of fields for each such piece of data from other properties.
This simplies the struct by instead having it contain the set of computed values (for a given element) that is being populated and classify properties into "early" and "other", such that the only dependencies can be from "other" to "early". We iterate applicable_declarations twice, first cascading "early" properties then "other". Unfortunately, it’s not easy to check that this classification is correct.

This fixes a bug in line splitting caused by the following actions when
`LineBreaker::split_line_at_last_known_good_position` is called:
1. Push some number of previous fragments onto the front of the work list.
2. Push the current fragment back onto the front work list.
This resulted in the work list being out of order. The correct order is
action 2 followed by action 1. Fixes#9830.
This fixes the border-end calculation for table rows whose borders are
collapsed with rows in different rowgroups. The border collapsing code now
uses an iterator that yields all the rows as a flat sequence, regardless of
how they are grouped in rowgroups. It gets rid of
`TableRowGroupFlow::preliminary_collapsed_borders` which was never correct.
(It was read but never written.)
This may fix#8120 but I'm not 100% certain. (I haven't managed to reproduce
the intermittent failure locally, and my reduced test case still fails but in
a different way.)
The <strong> element has a different font weight by default. This means that the line height
is slightly different from the ref test. In normal Servo this doesn't matter due to how the
default snapping works.
However, in both WebRender and Firefox, this results in the reftests being one pixel different.
Setting the font weight to be normal makes the reftest pass in Servo, WebRender and FF.
