I pushed out the requested change but without any new tests.
I've tried a bunch of things based on my intuition in an attempt to write some tests for this change and nothing - from my attempts - managed to hit those lines with a non-NoInfer substitution type. So I went to recheck if I could observe some cases like this using the existing test suite:
isExcessPropertyCheckTarget/isKnownPropertydidn't observe such substitution types at allisWeakTypehas observed it indeeplyNestedMappedTypesandconditionalTypeDoesntSpinForever. Those are complex enough that figuring out a test case based solely on them might take me a longer moment.There was a problem hiding this comment.

Yeah, it's not going to be easy to come up with a case where it matters and I'm fine going without.
