The takeSnapshot callback in -[_WKThumbnailView _requestSnapshotIfNeeded] assumes that taking the snapshot will always succeed. If it fails and the callback receives a null ShareableBitmap::Handle, as can happen if the WKView is closed while a snapshot request is pending, the callback will dereference null.
