[Bug] Command autocomplete highlighting mismatches input pattern in slash commands

Bug Description
attempting to log in via the slash commmand does not properly perform command highlighting. typing "/log" matches "/logout" (unsure what the natural ordering for commands is) but once the command becomes "/logi" it still hovers over "/logout" which is unintuitive and hard to use for the user.
