Expected behavior If I select "everything" in textarea via CTRL+A and delete it, it would be nice to leave content really empty (do not leave some br/div still in the textarea)

Actual behavior Content is "empty" if you look to text area, but in the real there are some div/br tags which are not visible (also br), but you can do empty via backspace key. Nothing change for eyes, but some tags go out.

If you want detect if you have or haven't filled text in wysiwyg area it can be little bit complicated with hidden div/br.
