Class comment? It's not clear why it's needed at all with one static method :)

Got it.
There should be more I believe. Also, it's a method that is used by a few
elements.

+  STATIC_ONLY(MediaControlElementsHelper);
+
+ public:
+  static bool IsUserInteractionEvent(Event*);
+};
+
+}  // namespace blink
+
+#endif  // MediaControlElementsHelper_h
