I can investigate this on Monday, or we can just revert that patch for now - it's only a small patch, that should be easy to revert, and then re-merge later on with a fix.

Making this a P2 until we know more.  Glenn -- let us know what you find out on Monday.  Thanks.

Opened a WR PR to revert this patch, for now. We can follow up with a correct patch later on.
