Changing a tooltip resets the timeout. In one particular case,
while rolling, AudioClock::set() is calling set_tooltip() at a rate
faster than the tooltip timeout and prevents tooltip from showing at all
(even if there is no actual change to the tooltip text).
Alas, there is no trivial fix for this UI side and there may be other
such cases. A central check is more than practical.
