About TextArea height can't adjusted in html gui of Alteryx SDK

[flying008]

Dear all , hello !

I want to set the textarea height to 2 rows in html gui, but it always show 1 row, if string length more than 1 row, the textarea can't display complete, and no way to drag the box size , so what's mistake in the below syntax ? @jdunkerley79 

<textarea id="regularExpression" rows="2" resizable="true" wrap="virtual" style="height:3em; resize:both; background-color: Aqua;"></textarea>
