* 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)
* Also a touchmove, touch+hold, and anything other than a tap is not supposed
* to turn the controls back on on a mobile device.
