Bisection isn't very useful because it basically just says "this has always ICE'd since the precise capturing rework" in #126049.

cc @compiler-errors since you know best about the precise capturing feature.

Other MCVE (from the duplicate #141575):

trait A<T: use<Self>>{}

demonstrating that this affects type parameters in general, not just the Self one.
