/f who username does not work to look up Bedrock players - still an issue

My old report was marked as "fixed" but this is still an issue. If you run "/f who name" with name being the IGN of a Java player, it will tell you if they are in a faction, and if so what faction they are in. However, if you run "/f who RSIsGreat" with a star before "RSIsGreat" (my Bedrock alt), it does not tab complete, and you get this message. See screenshot
