RTE insterting extra symbol in {sql} query

Apologies if this is a duplicate, but I just came across it and couldn't find a match after a llttle searching on jac

Using the sql macro, switching between the RTE and wikimarkup will break the query by adding extra characters:

Wiki markup:
count(*), x != 2 

After going to the RTE:
count(*y), x/!= 2 

It adds a 'y' character after the star and a '/' character before the exclamation point.
