TextArea component

What did you expect to happen? What happened instead? What would you like to see changed?

In the TextArea component when the props invalid is passed as true and the props invalidText is passed with any string value I'm expecting to see the error message with an Alert icon on the left.

The Alert icon on the left of the error message is shown in the other input fields like: TextInput, RadioButton components.

At the moment the error text is displayed correctly but there's no Alert icon.
