Trigger "mobile quick action" only when start swiping down from tabbar

Thru long usage I have adjusted my habits so that happens to me less often, but I would like this very much.

It would also potentially enable closing the keyboard by scrolling down, as is standard on iOS (I don’t remember if also on Android). There was a request for that feature, but it was implemented in a non-standard way (as a command assignable to Quick Action) because Quick Action prevents the standard behavior used in other apps.
