cc @llvm/clang-area-team we might need some guidance on how to handle this. It looks like the original change was meant for a cherry-pick on a release branch to fix an old regression (https://github.com/llvm/llvm-project/issues/160513) but it also led to a bug on ToT (https://github.com/llvm/llvm-project/issues/164866).
