Block trackpad until gesture is done

I have a two finger swipe gesture with repeated action assigned to changing volume while mouse's over menubar. I lift my fingers, but if my palm touches the trackpad the action keeps performing until I lift my palm. Palm handling is on, but the issue persists. Is there a way to fix it or is it an expected behavior?

I once asked something similar. If I'm not mistaken, the answer was that you could theoretically "disable" the lower part of the trackpad, where the palm of your hand is, with the Advanced Conditions. But I don't want to do that. So I just lift the whole hand. I hope I'm not saying anything wrong :slightly_smiling_face:
