 * Play a sound when a help dialog opens.

 * Opening only: `helpDisplay` also changes when the player walks through the items of a same dialog with the
 * previous/next arrows, and that is one continuous consultation, not a second opening. The ref holds whether
 * a dialog was open rather than which one, so those steps are silent.
 *
 * It starts undefined, and the first run only records the state it found. A player reconnecting while a help
 * dialog is open receives it in the game state, and that must not sound like they just opened it.
