Yeah, this is intentional, button inhibtiros are bound to the active
session, as they are about processing input keys, and only the fg
session should be able to do that.

Why precisely does your original session inhibit the lid switch? If
you want to turn off the lid switch then turn it off properly,
inhibition is not really about turning something fully off. It's about
temporarily making logind not process it, for example, because you
want to process it yourself or so.

GNOME for example never inhibits the lid switch, because there's
really no reason to. Why does your DE inhibit it?
