In C++, I think we can use an enum instead of Strings for the actions. This
might actually simplify things a bit.

+    action = action.isolatedCopy();
+    if (!temp.isSafeToSendToAnotherThread() || !action.isSafeToSendToAnotherThread()) {
+        exit(42);
+    }

+    m_workerGlobalScope->thread()->workerObjectProxy().postTaskToMainExecutionContext(createCrossThreadTask(&ListOfElements::execute, AllowCrossThreadAccess(page->m_listOfElements.get()), action, temp, m_keyframes, m_timingInputDictionary));
+}
+
+void MockAnimationPlayer::reverse(ExceptionState & es)
+{
+    String temp = m_id.isolatedCopy();
+    String action = "reverse_element";
+    action = action.isolatedCopy();
+    if (!temp.isSafeToSendToAnotherThread() || !action.isSafeToSendToAnotherThread()) {
