TestContextMenu has been broken for as long as I remember. It's trying to load an MPEG-2 video file and confirm that right-clicking on it shows media element context menu entries. Doesn't work on Fedora. Dunno why, since Fedora actually can play MPEG-2, but I don't care to investigate. Switch it to WebM.
