* on the video turns the controls off. Then the `touchend` event bubbles up to
* the player. Which, if it reported user activity, would turn the controls right
* back on. We also don't want to completely block touch events from bubbling up.
* Furthermore a `touchmove` event and anything other than a tap, should not turn
