Thank you for your report. This has already been fixed in bleadperl, and
so the fix will make its way into 5.14.0.

The RT System itself - Status changed from 'new' to 'open'

@cpansprout - Status changed from 'open' to 'resolved'

Can you point to a commit there this was fixed?
Is it possible to backport this change to 5.12?

This was fixed by e5c69c9, which has been approved for cherry-picking by
three committers (including David Golden).

It won’t apply without e3d2b9e, however, which was rejected by David Golden.

So could David un-reject it? Or should e5c69c9 be tweaked and applied? I
don’t feel comfortable doing the latter, but would not mind if someone
else did it.

From @xdg

I had rejected in cherrymaint a set of things that came in from Dave M
that seemed related. If this one can be safely pulled out and used
separately, I have no objections to that.

From @rjbs

The required commits have been cherry-picked into 5.12.3-RC2, likely to ship January 22.
