When a IPv6 is making a edit, the link text on the Watchlist is in lower case, but the link to Special:Contributions has the ipv6 in upper case in it.
That is confusing. It is possible to have the ipv6 showing all the same on each place? I have no problem, when the user page of a ipv6 is under the lower case name, that looks better, than the upper cases.
