           Summary: [GStreamer] Layout test
                    media/media-higher-prio-audio-stream.html is crashing
                    with GStreamer-CRITICAL **: gst_object_get_name:

Since enabling fatal criticals for layout tests, test media/media-higher-prio-audio-stream.html is crashing in MediaPlayerPrivateGStreamer::handleMessage with the following error:

STDERR: invalid uninstantiatable type '<unknown>' in cast to 'GstElement'
STDERR: 
STDERR: (WebKitWebProcess:30961): GStreamer-CRITICAL **: gst_object_get_name: assertion 'GST_IS_OBJECT (object)' failed

Updating expectations accordingly. Backtrace:
