Tag Sets
Summary: When I click on a Tag (that isn't actually a Thing), the resulting page should show me all the references to that Tag. It doesn't seem to be doing so, at least in this example. Why isn't that working?
Okay, this is now annoying the hell out of me, now that I've added Features to the Issues Space. Kicking this up to High.
