Unlike other components that we use Hammer on, the tooltip won't show up at all on a touch device if Hammer isn't loaded. These changes add a fallback to using a
touchstart
event to trigger the tooltip.Also fixes the
_manualListeners
not being cleared on Android.Note: doesn't include a unit test since we don't have a way of removing Hammer in tests.
Fixes #13536.
