nbd,

I found /changeset/41828.html. Is this change in BB RC2?

comment:4 Changed 3 years ago by anonymous

The issue cannot be reproduced on trunk. I figure it is fixed by r41828. And checked latest 14.07 branch, it is on r42068 already, so should be fine.

How can I close this ticket? Looks I don't have the permission to do that.
