Run the testcase.
Press button "Press to show"
In popped window press with mouse button "Press to hide"
Note, that the frame named "test frame" does not get focus. The only
way to get focus to the frame is to switch to another window
and back to frame.

Seeng the debug output we can say that focus was not transferred from the
hidden window.
