FAB list buttons color input not working since RC3

[Manduro]

Short description of the problem:

Buttons inside an ion-fab-list should use color correctly. It's a css issue because the color specific styles are there, but are overridden. In RC.2 this was working fine.

<ion-fab right bottom>
  <button ion-fab color="primary"><!-- This button shows blue correctly -->
    <ion-icon name="add"></ion-icon>
  </button>

  <ion-fab-list side="top">
    <button ion-fab color="primary"><!-- This button shows grey instead of blue -->
      <ion-icon name="checkmark"></ion-icon>
    </button>
    <button ion-fab color="secondary"><!-- This button shows grey instead of green -->
      <ion-icon name="close"></ion-icon>
    </button>
  </ion-fab-list>
</ion-fab>
