patak@osma @elk @daniel Yes, we added the click to remove (with a red color feedback) as a temporal UI to let folks at least work around this issue. But it isn't good. We have two options, one is to avoid a fancy UI for mentions when editing and just show the raw text (I would be fine with this), or the other is to properly do a mentions UI that has each mention as a proper badge with a cross remove button, and a plus button to add a new one, etc.
