Subject: [PATCH] tst_QComboBox: fix popupPositionAfterStyleChange() FAIL on
 Kubuntu 20.04

On my machine, the window manager opened the QComboBox always at y = 0
(top edge of the screen), where the popup, being confined to the
screen geometry, had no chance of "open[ing] up centered on top of the
current index".

Fix by centering the widget on screen.

Pick-to: 6.9 6.8 6.5
