This has been fixed in V15 with #17288, but I wonder if we can cherry-pick that back to V13. I will make sure it gets included in one of the upcoming development sprints.

This issue turned out to be something completely different than what I originally thought in my previous comment. I have submitted a potential fix in #17667.
