cross realm whisper-click not working

[neftha]

When clicking players in the list that are on the same realm - works nice / able to chat (using wim as well).

But when clicking on a player on a different realm (cross realm guild) - a wim window opens, but seems to try a character on the same realm / without realm name added.
Any chance to make players on different realm clickable incl. their realm name? Would be great :-)
