Marked as fixed.

Trying to reproduce this on my 4.2.2 (v17) Nexus 4. Added this drawable:

<transition xmlns:android="

http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/test_drawable_blue"/>
<item android:drawable="@drawable/test_drawable_green"/>
</transition>

where blue/green drawables look like this:

<shape
xmlns:android="

http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<size
android:width="@dimen/drawable_large_size"
android:height="@dimen/drawable_small_size" />
<solid
android:color="@color/test_blue" />
</shape>

Then added this test:

@Test
public void testMutateTransitionDrawable() {
Drawable drawable = ResourcesCompat.getDrawable(mResources,
R.drawable.test_transition_drawable, null);
assertTrue(drawable instanceof TransitionDrawable);

Drawable mutated = drawable.mutate();
assertTrue(drawable instanceof TransitionDrawable);
assertTrue(mutated instanceof TransitionDrawable);
}

It passes on the device. Going to also try on other earlier devices a bit later in the day once they are charged.
