Normalizing Binder { value: <impl std::future::Future<Output = ()> as std::marker::Sized>, bound_vars: [] } without wrapping in a `Binder`

Bonus: using an extension trait with a Future blanket impl instead of the drop function gets you a slightly different ICE (not as minimized, this is closer to the code in the repo triggering this): playground
