Oh, right, I did have a new test I meant to add, but that's a better place for it - so I've added that test coverage in https://github.com/llvm/llvm-project/pull/96699/commits/b3facc9dffc762e3cef93886df23026d502afcae

(I'm out for the day, so if anyone happens to approve this and feel like pressing the "squash and merge" button that'd be swell, otherwise I'll get to it when I have a chance/tomorrow)
