Reviewed by Aditya Keerthi.
Make a couple more adjustments to the dynamic viewport height expansion
heuristic:
1. Only compare the height of the fixed-position container against the
fixed-position layout rect,
instead of the area of the rects. This allows the viewport to shrink in
cases where there's a
tall fixed-position popup that's intended to cover the full height of the
viewport, but doesn't
take up the entire width of the viewport.
2. Once one or more large fixed-position popups are found, check if any of the
nodes surfaced via
area-based hit-test are contained within any of the popups, rather than
trying to check whether
any one of the hit-tested nodes is (itself) a large fixed-position popup.
This prevents a false
negative in the case where a large fixed-position element contains a child
element that covers
the entire fixed element.
