> should we force the theme to be `GTK_THEME=Ambiance` ?

Maybe yes, though Adawita (not Ambiance)?

Considerations:
- Neither Ambiance nor Adwaita is what modern Ubuntu uses (yaru), so from that perspective there's no strong reason to prefer either one. 
- Given that Ambiance is the default on Ubuntu, it must be missing in some of our test runs, or else it would have been used, right?  So setting it in GTK_THEME might not help.
- But `GTK_THEME=Adwaita` would probably help (it should consistently be available  since it's part of base gnome).
- However, that won't help with bug 1894445; changing GTK_THEME doesn't change the system icon set.  (Maybe that's ~fine, but it's still weird that our system icons are variable and might cause some other variability outside of that bug...  Likely all part of the same underlying strangeness.)
