// A clip in the post a reply answers (the "Replying to" card in the
// Conversations view) isn't one of the feed's own, so the media pager can't
// take it: a tap on it, or the player's own full-screen button, puts it full
// screen the browser's way. Both used to do nothing at all — the full-screen
// handler took the clip back out of full screen for a pager that then
// wouldn't open.
