Othesus, you are the master of LU notes links.
At least on Runnyeye, which does not have the patch yet, the command is different and not bugged:
/escape_opens_start_menu false
to disable this. So if it's different on US servers they changed it with the latest patch.
Edit: Checked this on Nektulos server. The command is as I posted, but you are right the bug is there.
