 `MediaError` got a new property `message` that might contain system
 information, see: https://bugzilla.mozilla.org/show_bug.cgi?id=1322606 and
 https://github.com/mdn/dom-examples/blob/master/media/mediaerror/main.js.

 We should find out whether that's the case and if so probably just remove
 that part.
