Yeah, we've seen this before -- need to track it down. I don't think it's related to this PR, but I'll trigger a CI re-run to check. |

Summary
Tracked structs have some issues with fixpoint iteration in Salsa, and there's not actually any need for this to be tracked, it should be interned like most of our type structs.
The removed comment was probably never correct (in that we could have disambiguated sufficiently), and is definitely not relevant now that
