REGRESSION (303055@main): Intersection Observer fails with zoomed visual
viewport
rdar://168143635
https://bugs.webkit.org/show_bug.cgi?id=306372
Reviewed by Simon Fraser.
303055@main removed some calls to RenderView::localToAbsoluteQuad, because
those
requires access to the root's RenderView, which is inaccessible with Site
Isolation
enabled. However, this breaks Intersection Observer with pinch-to-zoom.
Pinch-to-zoom
applies a scaling transform on the RenderView, and localToAbsoluteQuad
accounts for
the transform. This patch temporarily reverts 303055@main while we figure
out a
better solution.
