Using a custom theme leaks 10-15 MB per hour

Bug description:
[ Impact ]
gnome-shell has a memory leak, which causes the user's memory to be
gradually consumed after several days of gnome-shell being open with
some themes, even when no actual user-visible tasks are being
performed.
[ Test Plan ]
1. Install the White Sur theme from
https://github.com/vinceliuice/WhiteSur-gtk-theme
2. Enable the theme in Gnome Tweaks.
3. Start tracking memory usage in a format that can be easily graphed.
Include any data and graphing scripts used in your tests in this report.
4. Keep gnome-shell open for 2 days, and keep the machine idle
5. Save graph of memory usage
Perform these steps on both an unpatched system and a patched system
and compare the results.
[ Expected Behavior ]
Memory utilization graph should be relatively flat at start and end of
experiment
[ Actual Behavior ]
Memory utilization graph increases roughly linearly with respect to
time
[ Where problems could occur ]
This patch changes which memory management primitive is used in one
place, which could theoretically result in a user-visible crash if
improperly implemented.
[ Other info ]
This is to track upstream bug:
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/8509
which seems to be a regression starting in gnome-shell 46.0.
