Winecfg dropdown box

Opening a dropdown list box and then moving the frame around, the pop-up list
view stays open at the same place, see attach screen shot.
This is not same as Windows; when frame is moved, drop down closes itself.
Tried with winecfg application on Wine 9.0 & Ubuntu 20.04.6, but can be
reproducible with other versions as well.
