Subject: [PATCH] Fix ui/forms/input component for tag: :textarea

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea
In HTML, the initial content of a <textarea> is specified
between its opening and closing tags, not as a `value`
attribute.

Therefore we must set `content`, rather than passing `value` for
 text areas.
