It does (to my untrained eyes) seem broken but not for the reason I think you're suggesting.
Patching to add adwaita-icon-theme would be the same as me installing it manually, right (just making sure my understanding's correct)? I tried installing Adwaita icons when testing things out so I don't think that's the issue.
The issue seems to be that icons such as Papirus and Delft aren't using their own folders; instead, they seem to be using Adwaita's (maybe via the gnome-icon-theme package?). I think the images I'd attached better demonstrate the situation than I can, with words; some of the icons in the icon selection window show the right icons for the theme while other ones (namely the folders) default to the ones in the Adwaita icon theme.
It seems, to me, like possibly an issue with the icon themes, themselves? I'm not sure why it would but it's not an issue with the Adwaita icons, themselves; they load fine. It's the other icons which aren't using their full range of icons and are, instead, defaulting to another icon theme for some of their icons.
I…couldn't say why (unfortunately…) but it seems more to do with the other icon themes and less with the Adwaita icons, themselves.
