This looks like a gtk crash that's fixed upstream in https://gitlab.gnome.org/GNOME/gtk/merge_requests/1114 . Let's get the fix backported.

I went ahead and backported this to gtk3-3.22.30-6.el8

No crash when I updated to gtk3-3.22.30-6.el8.x86_64

Since the problem described in this bug report should be
