Bug Description

Running GNOME Calculator (or System Monitor, for example) runs the app with Adwaita theme instead of Yaru when in the live session. This seems to resolve itself when used in the real session.

Steps to reproduce:

* Launch a live USB stick in a VM (note: you might need to use nomodeset until that is fixed)
* Open any of the seeded snaps and note that the theme is wrong.
