+    Test of animation sandwich priority based on syncbase dependencies.
+
+    Test that we don't filter out a change to the timing model that does not
+    affect the start time of an interval but which DOES affect the dependency
+    chain.
+
+    Given the arrangement below, 'a' will have higher priority, as it is later
+    in the document. However, via script, we make 'b' dependent on 'a' giving
+    it a higher priority whilst preserving the interval times.
