Bug in z-Order of MDI Interface

Andy314

Helle, I found a strage and very unpleasend behaviour of the MDI-Window/Interface. You can reproduce the error with the included standard MID-Example:

Open Window1
Open Window2
Open Window3

The windows are then in the Z-Order 1 2 3.

Then close Window 3.
What do you expext ?
I expect that window 1 2 hold it z-Order and window 2 ist on top now.

BUT:
Window 1 pops to top.

I tested it with Qt 5.15.1 MSVC 2019 64 bit.

This is very never, espacialy for full screen mode of the mdi-clients.

It seem that always the first created Window pops up.
