If there is a "pending" tap (due to Commander needing to wait and see if a second tap is going to happen) with any number of fingers and you perform any gesture other than the second tap, then the action bound to the original single tap will trigger immediately.
This matches behavior on iOS . For example, if you have UC configured so that 1 finger single tap is assigned to "click", 1 finger drag is assigned to "scroll", and 1 finger double tap is assigned to something else, then tapping a button and then quickly performing a drag on a scrollable area (within the time limit for a double tap) will cause the button to be clicked and the scroll area to be scrolled.
