Bug 1516292 - Use isSameNode() to compare mozFullScreenElement and the video host element. r=edgar, a=RyanVM This does what's done in bug 1505547 but in a different way. For some reason, access shadowRoot.host in the function can trigger an assertion. this.video is a Proxy so it cannot be compared, but all its methods are proxied.
