When plain text is posted into the html editor it appears to be automatically wrapped with font tags adn size attributes even if I have the font and size options disabled from the toolbar. I do not believe the font and size attributes are existing formating for the text. I think the html editor is adding them.

Im hoping at some point someone will create an extension for the htmlEditor so that we can paste text with formatting and have it converted to plain text. but in the meantime I don't understand why pasting plain text doesn't work either.
