Follow-up to 3622f06bed

Work around 3D scene focus after de-activation of the main
window without having to resort to CallAfter(), which breaks
on Linux with some window managers that follow mouser cursor.
Fixes #5620 #6870 #6992

3622f06bed was not a correct solution,
it broke focus for non-modal windows.
Fixes #7419

The actual issue seems to be caused by wxProgressDialog not playing
well with modal dialogs closed just before wxProgressDialog opens.
If wxProgressDialog parent was not a main frame, keyboard focus
was not restored correctly after the wxProgressDialog closed.
