Thank you for your feedback. However, I recommend against merging this test. The linked pull request (https://github.com/llvm/llvm-project/pull/140529) introduces a new feature rather than correcting a bug. I believe it's inappropriate to add a test covering a new feature and then submit a separate pull request to "fix" it.
