Yeah, the visual editor (source mode) on UCP which happens to be on the flipside of the source editor on legacy is a complete disaster.

Once the majority of the wikis I administrate are on UCP, I'll be changing my preferences so that I'll have the UCP source mode enabled. Unfortunately that also means that I'll have to enable visual editor on legacy.
