under 5.8 opening the Drawer I always could close the Drawer by tapping outside of the Drawer
under 5.9 the (opened) Drawer looks the same (space outside Drawer is dimmed),
but tapping outside doesn't always close the Drawer.
sometimes after some taps, sometimes never, sometimes immediately
under iOS I'm getting this after opening the Drawer by dragging:
and this after some taps outside drawer if I was able to close the Drawer:
under Android no output like this
on MacOS clicking with Mouse works, so it's a touch problem
I verified comparing QtQuickControls2 Gallery APP from 5.8: tap outside Drawer closes Drawer, Gallery from 5.9: tap outside doesn't close the Drawer
tried explicitely setting modal true or some other close policies, but Drawer wasn't closed reliable
while the Drawer cannot be closed tapping outside, the tap event goes through to the underlying Page and so user can hit a Button by accident.
Found a (ugly looking) workaround and inserted a fake Popup between Drawer and underlying StackView Pages. Now user cannot tap on Buttons from Pages below, but unfortunately also cannot "see" the content below. couldn't figure out a way to make this fake Popup transparent
