Undocked windows lose focus after dialog closes

[mueschel]

If I edit tags of a POI in the undocked "Tags/Memberships" window, the window often loses focus to the main window after editing a tag.

That means I can't use the keyboard to navigate to the next tag to edit, but need to use the mouse to reselect the window before I can continue editing. Most annoying effect: Pressing 'delete' to remove one tag often deletes the whole POI, depending on whether the focus switched or not.

What steps will reproduce the problem?

1. Open the "Tags/Memberships" in an undocked window
2. Edit some tag, close dialog
3. In ~ 50% of the cases the focus stays on the window, in other cases it switches back to main window

What is the expected result?

Focus should stay on the current undocked window

What happens instead?

Focus switches to the main window.
