Emilio Cobos Álvarez ac2f80304e Bug 1568536 - Don't propagate viewport styles from display: none or display: contents elements. r=dholbert
Resolution is at:

 * https://github.com/w3c/csswg-drafts/issues/3779#issuecomment-481762912

Tests are at https://chromium-review.googlesource.com/c/chromium/src/+/1547974,
I'll make sure to wait until they're in the tree and ensure they're passing.

Note that we need to ensure in the frame constructor that the document element
is styled _before_ calling UpdateViewportScrollStylesOverride(). This saves
duplicated work (since ResolveStyleLazily throws away the style).

ResolveStyleLazily already returns out of date styles, unless the element is not
styled yet, or is in a `display: none` subtree, in which case it computes and
returns a new (up-to-date) style.

So the switch to the FFI call only should change behavior for the display: none
subtree case (since we ensure the unstyled case isn't hit by styling the
document earlier). But that case is one of the cases we're interested in
changing, conveniently.

Depends on D40080
