This is also the cause for the failures in tests/ui/traits/const-traits/predicate-entailment-passes.rs. Where clauses must be equal, which kinda makes the GATs in that test useless.

new solver test without enabling the new solver?
also, instead of adding a new test, maybe revisions and a comment in tests/ui/generic-associated-types/issue-91883.rs are enough?

Kinda prefer an explicit test. 91833 is a mess. I'll add flag, tho, whoops.

See below for why I ripped out the GATs from this test.
