autogrow leaves garbage in DOM after removing it

[JohannRosenberg]

When I use the autogrow on a textarea, it appends the following to the DOM:

<div style="position: absolute; top: -10000px; left: -10000px; width: 427.109px; font-size: 14.832px; font-family: system-ui; font-weight: 300; line-height: normal; resize: none; word-wrap: break-word;">...</div>

When I remove the textarea from the DOM, the above div still remains in the DOM. This continues to accumulate each time I add a textarea and remove it. You should change the following line:

$self.change(update).keyup(update).keydown({event:'keydown'},update);

to be this:

$self.change(update).keyup(update).keydown({event:'keydown'},update).on("remove", function(){
                shadow.remove();
            });
