[Bug 34315] HWND_NOTOPMOST makes window disappear behind other windows

I did a test where I set HWND_NOTOPMOST after an additional delay.
As soon as HWND_NOTOPMOST is set, the window falls behind the window that is
focused, so it does not seem to be conceptually related to the WM preventing it
from stealing focus as it is already TOPMOST. Its just that NOTOPMOST triggers
a re-ordering, that should not happen.

In Windows its possible to have program F infront of program B while program B
has focus and keystrokes go to program B.

Is that possible in Linux?
