-<!--
-`iron-autogrow-textarea` is an element containing a textarea that grows in height as more
-lines of input are entered. Unless an explicit height or the `maxRows` property is set, it will
-never scroll.
-
-Example:
-
-    <iron-autogrow-textarea id="a1">
-      <textarea id="t1"></textarea>
-    </iron-autogrow-textarea>
-
-Because the `textarea`'s `value` property is not observable, you should use
-this element's `bind-value` instead for imperative updates.
