            Bug ID: 166957
           Summary: [WK2][Cocoa] Avoid null dereference in FullScreen
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Crash tracing statistics indicate that the 'WebVideoFullScreenManager::didSetupFullscreen' encounters stability issues under certain conditions.

We do not have a reproducible test case showing this behavior, but code inspection indicates that the page values in the completion Block were not being referenced consistently with other methods in the same class. It also did not account for the possibility that the page object had been cleared between starting the dispatch and when the block actually runs.
