REGRESSION(289248@main?): Null LocalFrame dereference during render tree
teardown
https://bugs.webkit.org/show_bug.cgi?id=289096
rdar://145408212
Reviewed by Simon Fraser.
Crash data indicates that dereferencing a null LocalFrame during render tree
teardown has recently become
more likely. All crashes occur beneath Document::willBeRemovedFromFrame, which
constructs a
NavigationDisabler that previously held a RefPtr to LocalFrame but, after
289248@main, now holds a
WeakPtr. Revert it to a RefPtr to speculatively fix this crash.
