There are a lot of bugs regarding to cross-references (60360, 84339, 92688, 98462, 106532 and many more). I think there should be a Meta-Bug to collect them.
good idea, anyway nothing prevents you to create a meta bug about it.
I mean, you don't have to ask permession for it...
any user can do it, even you.
so let's close this one as "INVALID" and feel free to create that meta-bug.
