That's another issue we are having with the content interface in context of getting themes to work with snaps.
In the case where the gnome platform snap is being used we have that configuration
that snaps includes a slots giving read access to the theme directory
the platform is mounting the themes so those apps don't have to care about the technical details, which means
- the platform has a plug mounting the theme
- the platform has a slot that gives read access to its content
- the theme is in a subdirectory of the platform shared directory
the client snap mounts the platform
so in summary
[gtk_software_snap, gnome plug] -----> [gnome slot, gnome_platform_snap, theme plug] -> [theme slot, theme_snap]
But it looks like the gtk snap doesn't see the content of the theme, the gnome platform content is correctly mounted but it includes a theme directory which seems to be only the empty mountpoint and not have the content of the theme snap.
Does anybody know if that's the expected behaviour or a bug? If so in what component?
