// Projections cover type parameters if they normalize to a (local) type that covers them.

// This ensures that we don't perform an overly strict check on

// projections like in closed PR #100555 which did a syntactic
|
|
// check for type parameters in projections without normalizing
|
|
// first which would've lead to real-word regressions.
