--paper-input-container-invalid-color not applied to label

[nicolethenerd]

Description

In the documentation for paper-input-container, it says that --paper-input-container-invalid-color will be applied to the label and underline color when the input is invalid. However, in practice it only applies to the underline color - the label color does not change.

Expected outcome

The label turns --paper-input-container-invalid-color when an invalid input is entered.

Actual outcome

The label color stays the original grey.
