IPv6 adress and port will be used without square brackets

Hello,
when I try to use "Go" --> Connect to Server (SSH) and type an IPv6 address without square bracket in the field, it will be used in the URL bar without brackets. If the IPv6 address is shortened with 2 colons (::), the IPv6 will be ambiguous if a specific port is being used.
Adding square brackets to the IPv6 address will fix the problem. That should be automatically done when entering an IPv6 address without brackets.
sftp://user@[2001:xxx::xxx]:123/home/user #works, address and port distinguishable.
sftp://user@2001:xxx::xxx:123/home/user #does not work, ambiguous address

kind regards
