TextInput's behavior diverging from Material's guidelines

[ghost]

Current behaviour

TextInput's states are not behaving quite like Material's. When the component is on the "idle & filled" state, the label and bottom line are still with focus effect.

Expected behaviour

When the component is on the "idle & filled" state, the label and bottom line should be grey.
For reference, check the text field's guidelines here.

Also the disabled state should have a dashed line instead of solid.
