Lifetimes bounds added to returned impl Trait does not seem to be considered by the compiler.

Example: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=02f184ddb3ce9d04c049c93c9d8b25b5

I would expect the above example to compile: wrap is defined to return a 'static Future, so why is the compiler saying that it should have the same lifetime as &self ?

The issue does not manifest when returning a concrete type like MapErr or BoxFuture<'static, Reply>,
