[iOS] Adjust the viewport expansion heuristic to better detect full-page
modal containers
https://bugs.webkit.org/show_bug.cgi?id=276849
rdar://132160090
Reviewed by Abrar Rahman Protyasha.
Make some more adjustments to the layout viewport expansion heuristic:
- When hit-testing to see if there's a large modal container covering most of
the viewport,
perform an area-based hit-test in the entire viewport. This avoids a false
negative in the case
where the center of the viewport hit-tests to a smaller fixed-position
container that does not
cover the screen.
- Don't re-expand to double height after shrinking, to avoid cases where the
viewport height might
thrash too frequently.
