This was still marked as a bug in 4.3 in the "Summary" section of the
bug.  Given that this fixed, I've removed the 4.3 marker there.  In

I think you meant 29877?  In any case, thank you!

I'm going to leave them open, but I've added a link to your message to
the audit trails.  Optimistically, someone might miraculously fix them,
but it's very helpful to know that that's going to be unlikley.
