CRASH in MobileSafari at WebCore: WebCore::Region::intersects
https://bugs.webkit.org/show_bug.cgi?id=263038
rdar://116794024
Reviewed by John Wilander and Wenson Hsieh.
Crash logs indicate a new crash originating in
`collectDescendantViewsInRect()`, where a null return from
`RemoteLayerTreeNode::forCALayer(...)` is dereferenced without a null check. A
null check was added to `collectDescendantViewsAtPoint()` in 268566@main, and a
similar null check will be added here.
Verified through code inspection that no additional unguarded uses of
`RemoteLayerTreeNode::forCALayer(...)` remain after this change.
