I'd like to fast track this. Please 👍 if you concur.

Marking as FLAKY until we solve the underling issue.

We also have the option of fast-tracking #25896 if you think there is urgency to resolve this? It's not a complex change, so I think this should be okay.

I'll verify that it solves the issue in a environment known to repro.

If you do want to merge this, please add a reference to #25512 in the commit message.

👍 with the magic of node-core-utils, it adds the Refs from the OP to the final commit message without getting all the

during review.

LGTM although obviously even better if the proposed solution works and we don't have to mark this as flaky at all.
