REGRESSION(255641@main): Web process crash in
WebCore::isDescendantOfFullScreenLayer when when fullscreening video on
reddit.com
https://bugs.webkit.org/show_bug.cgi?id=249689
Reviewed by Brent Fulgham and Tim Nguyen.
Currently we crash if the downcast here fails. The code inconsistently
expects it to always succeed, then checks for failure right below. Check
first. This seems to be all that's required to fix fullscreen video on
reddit.com.
