Label text wrong color in material theme when input is not focused

[KaneFreeman]

Bug

Package Version: 8.0.0-pre

Code

import { create, tsx } from '@dojo/framework/core/vdom';
import TextInput from '@dojo/widgets/text-input';
import Example from '../../Example';

const factory = create();

export default factory(function Basic() {
    return (
        <Example>
            <TextInput>{{ label: 'Input label' }}</TextInput>
        </Example>
    );
});

Expected behavior:

Label color should switch to primary ONLY when input is focused.

Actual behavior:

Label color switches to primary when input is focused OR input has a value. The current setup uses the active input to determine the color of the label instead of focus.
