Qubes OS release

4.2

Brief summary

From XMachina via Forum:
"Currently, the icons for the domains widgets is provided by the package xfce4-settings. I have tested this by installing and uninstalling this package and its dependencies recursively, and it is definitely this package. (Side note: I'd wager this is why these icons aren't on i3 [https://github.com//issues/7754].) The icons need to be provided in a different package and included or required by qubes-desktop-linux-manager.
The same applies for the package python3-gobject providing the individual progressbar/x/check for the Qubes Updater GUI."

Steps to reproduce

Install another DE - remove the xfce4-settings package - note that domains widget icons are no longer available.
Remove package python3-gobject - note that progress bar is not available in Updater GUI

Expected behavior

Necessary packages will be stated as dependencies

Actual behavior

Necessary packages are not stated as dependencies of qubes-desktop-linux-manager, and can be removed at will.
