Open multitasking view crashes at gala_icon_group_container_force_reposition
What Happened?
This happens on f8346f0d4a8577c1cf81036cc09324727cc98175 but not on d5e89a9fd1bdd3fdadfbd3c9a562e738684d048f, so probably some changes between https://github.com/elementary/gala/compare/d5e89a9fd1bdd3fdadfbd3c9a562e738684d048f...f8346f0d4a8577c1cf81036cc09324727cc98175 causes the crash.
I can trigger the crash on both x11 and wayland session.
Backtrace below :-)
Steps to Reproduce
- Open multitasking view from the dock.
Expected Behavior
No crash.
OS Version

It looks like I can't reproduce this issue with glib_debug option off when building glib, the option previously defaults to auto in < 2.82 and we have -Dauto_features=enabled in our meson build template, but upstream recently suggests disabling it in distro builds so now we have good reason to do that in NixOS :joy:
