This check takes place after all higher-ranked lifetimes have been instantiated. Checking the argument types ensures that the implied bounds due to argument types are correct. Checking the return type ensures that the resulting type of the call is WF. The previous code only checked the trait-ref, which was not enough in several cases. As this is a soundness fix, it is a [breaking-change]. Fixes #28609
