Tried modifying the source code of gnome-initial-setup, found that this issue cannot be reproduced, if the titlebar of the window (gis-assistant) is not set in the main (gis-driver) window.
I think this issue can be worked around in gis-assistant, but the root cause might be either gnome-initial-setup, mutter or libgtk-3
