Right, but this is the exact same thing as using
this._TextArea.getElement().firstChild.scrollTop =
this._TextArea.getElement().firstChild.scrollHeight;
You're working on the DOM element directly (either through
document.getElementById() or _TextArea.getElement()) and setting scrollTop to
scrollHeight. I would prefer the latter form since it saves you from the effort
of going through an HtmlEmbed.
