My work on Mobile Text Editing made it clear there is ALOT going on with low level Mobile UIs that isn't discussed or appreciated, e.g. it's far more than 'scrolling with your finger'.

I don't disagree with you but unfortunately, I can't reproduce your use case. But I"d like to! I think we SHOULD be discussing this more, expanding our UX vocabulary so we're all on the same page. If you wouldn't mind explaining (possibly in a DM if you prefer) how to get this problem to fire, I'd very much appreciate it.
