Log Message:
-----------
[Site Isolation] Animated images do not stop in an out-of-process iframe of a
hidden page
https://bugs.webkit.org/show_bug.cgi?id=321891
rdar://185064757
Reviewed by Simon Fraser.
When Site Isolation is enabled, we skipped over several operations in
out-of-process iframes,
because they only applied when a local main frame was present:
- resuming animated images
- calling show/hide on LocalFrameView roots (which affects scroll view state
and tiled backing
coverage)
(The path the pauses animated images isn't affected here--the animated image
timer loop already
self-pause when the images being animated go offscreen.)
Fix this by making this logic iterate through all root views rather than
applying to just the main
local frame view.
