Well, thank you for your example, but I would rather code a completely
custom combobox in QML than go this route
(even with my qml skills noobish at best it seems a more reasonable idea,
than coding a "widgets monster" )

And for the time being I will just stick with Controls 1 as I want to be
improving the core of my app
rather than spend weeks of my weekend time fixing UI problem introduced by
controls deprecation.

I just wanted to highlight the problem, that it is really, really too early
to cycle out V1.
And that combobox V2 is completely unacceptable on desktop. I still have to
see the "fusion" suggestion though
