Window Decorations disappear on selecting "Ubuntu Desktop" in the Settings app

[Agavi]

Window decorations (the "close"/"minimize"/"maximize" buttons) disappear when "Ubuntu Desktop" is selected in "Settings".

The app itself does not crash, and the close/minimize/maximize buttons reappear when switching to a different setting like "Appearance".

This seems to be ubuntu-specific. However I wasn't sure if there was a more suitable package to file this up against.

I tried setting the theme to "Adwaita" in case this was a Yaru bug and the problem seems to persist.

Thank you in advance
