REG: flicking TableView is broken

While trying to verify if QTBUG-104947 is fixed in 6.4 (it is), I found yet another one:
this time it only seems to affect TableView and ListView works correctly.
 
Let's say you have a flick active and you want to give it another nudge to speed it up a bit more: with the current 6.4 the flick stops dead if you release the finger/mouse outside of the TableView. My test case (see attachment) is a TableView with a Text on top (in a normal mobile/embedded app, this would be some sort of toolbar)
The first flick (starting from not moving at all), you can release the mouse anywhere: on the TableView, the Text ... heck even outside the X11 window: the list starts scrolling
 
But if you want to add a second flick to speed up or change direction, you are not allowed to release the mouse/finger anywhere outside the TableView (Text, outside the X11 window): if you do that the flick stops immediately
 
See the attached example, showing that ListView works, while TableView is broken: click the red area to toggle between list and table.
Flick a few times, ending the flick motion (a) on the view, (b) the red area and (c) outside the toplevel window
