Hmm, I can't reproduce that formatting selection issue: what browser are you using?

On headings - it certainly shouldn't change the existing heading spacing during an edit, but I don't think that is the complaint? I don't believe we touched any code around creating headings in visual mode, as far as I know they've always not had spaces.
