Clicking on Toolbar expand button twice reliably crashes Glade
When I click the toolbar expand button twice as shown in the video, I can reliably crash Glade 3.38.1 on MacOS Catalina 10.15.6.

In the video, I click the expand button twice, first on 0:08s, then on 0:14s. I see nothing else in the shell output other than that it terminated (see the last seconds of the video).
Maybe this is also related to the other toolbar editor woes I reported earlier today (#486). The file I'm opening in the video is attached here: frontend.glade
