Current behavior
InputTextarea doesn't automatically resize when textarea is initially populated with a long single line string. When the textarea is populated this way, the contents overflow once a user inputs some whitespace into the string, the textarea will then resize to the expected size.

Expected behavior
The textarea should be sized to the correct size initially without the user having to add input first.

Minimal reproduction of the problem with instructions
render the component:

<InputTextarea
            rows={5}
            cols={60}
            autoResize={true}
            value={this.state.longString}
            onChange={e => this.setState({longString: e.target.value})}/>
