Xinha: stylist plugin does not clean up HTML after removing a style

If I take a sample text, like "This is a styled text", and I add a style like div.example, I have :

--> <div class="example">This is a styled text</div>.

Now, I delete the style, I have :

--> <div>This is a styled text</div>.

Then, I want to add a style "div.other" only to "a styled", so I want :

--> This is <div class="other">a styled</div> text.

But instead, because of the empty <div>, it gives me :

--> <div class="other">This is a styled text </div>.
