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 ResolveStyleLazily already returns out of date styles, unless the element is not styled yet, or is in a `display: none` subtree, in which case it computes and returns a new (up-to-date) style.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