That's not a problem and I certainly wouldn't expect it to do so. I guess the silly notation is more widely supported than I thought, but, IMHO, it's a kind of poor choice of syntax outside of the limited use of displaying IPv4-mapped addresses for dual-stack socket connections displaying IPv4 connections in IPv6 format.
