Android SeekBar's progressBackgroundTint has no effect in API v21

Question

I'm noticing that when changing my SeekBar's progressBackgroundTint attribute, it gets completely ignored and has no effect. It doesn't matter what color I set it to; it always shows as gray on my device. Is this a bug with Android, or am I doing something wrong? When I switch the preview in Android Studio to v22, it gets properly set. But not so on v21.

My seekbar:

<SeekBar
    android:layout_width="300dp"
    android:layout_height="wrap_content"
    android:id="@+id/seekBar"
    android:max="100"
    android:progress="50"
    android:progressBackgroundTint="#ff4babe8"/>

I also tried setting progressBackgroundTintMode to all the known values, but still no effect. Anyone know why?
