// A touch on a feed clip that has been playing (its own controls up) opens
// the pager. Chrome on Android keeps such a tap for the player's controls —
// the page gets pointer events but no click — so the tap is read from the
// pointer events; here that is played out by swallowing the click. A touch
// on the control bar or the paused clip's play button stays the player's, a
// drag is a scroll, and where the click does come it isn't taken twice.
