1) Give element with touch-action:pan-x or pan-y set some momentum 2) During the momentum phase try scrolling the element again. If scrolling is already in progress, you can scroll to any direction.

This is true touch-action:none too. It is more noticeable with pan-x/y since you can use it to break out of the limitation easily.
