While removing ProjectionElem::Subtype we got ICE in one of the tests
https://github.com/rust-lang/rust/blob/cd40abae3619e82b6075dff3763615652ebad6a4/tests/ui/type-alias-impl-trait/normalize-alias-type.rs, this is a tracker issue for that, this ICE currently only happens #118477 but once it gets merged it will likely affect nightly users.
