In both cases I see stack traces in the browser console. I think the essential issue is that there are changes being made that aren't being picked up by the rule view. In the "overflow" case, resizing the textarea removes the commented-out overflow property; the rule view sees the size changes but doesn't notice that the property is now gone. In the "color" case, the edit in the markup view removes the element style entirely.
