It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

There is no update on the internal bug. But we do believe there is a real issue with dirty region management that is being patched in #31359. So depending on how quickly that patch is reviewed and landed, this PR may be unnecessary as we can fix forward.

Per the updates in the linked issue, this is not necessary.
