I have created a DIV with attribute contenteditable=true and appended children like "span" and "a" with attributes contenteditable=false. Wanted to test if the entire node be deleted with a single backspace and to my surprise Firefox couldnt delete the elements. Also this works as expected in all major desktop browsers except Firefox. Any clues on this or what could be the possible workaround?
