+    Test that we correctly handle "HasChanged()" flags when an animation becomes
+    inactive while its siblings haven't changed.
+    In this test case, we take our first sample at 1s, and both animations are
+    active. We take our second sample at 2s, and the first animation is the only
+    active animation. It hasn't changed, so we might think that we don't need to
+    recompose its target - BUT we *do* need to recompose, because the other
+    animation is newly inactive, and we need to reevaluate the animation
+    sandwich now that it's gone.
