Label and underline focus color not working

[AcerLaurinum]

Description

When you click on a paper-dropdown-menu the color of the label and underline changes for a moment but then goes back to the default color. paper-dropdown-menu-light does not do this and works as expected. Happens to me in the demo: https://www.webcomponents.org/element/PolymerElements/paper-dropdown-menu/demo/demo/index.html and elsewhere.

Expected outcome

The color of the label and underline should change when they are clicked and stay that color until they don't have focus.

Actual outcome

The colors changes for a moment but then goes back to the default.
