Hello,

This particular problem is a roadblock for my org. I see that a patch was submitted but it looks like it was abandoned. I've tested that patch and see that it resolves the issues that we are running into. I'm completely ignorant of the process here, but I'd like to know what is needed to get this bug resolved.

Thank you,
