You might want to add some class level documentation.

Done. Please check my wording.

+ public:
+  WebSurfaceLayerBridgeObserver() {}

[mlamouri (slow - plz ping), 2017/06/27 18:26:37]

Do you need the ctor here?

[CJ, 2017/06/29 19:51:34]

Done.

+  virtual ~WebSurfaceLayerBridgeObserver() {}
+
+  virtual void OnWebLayerReplaced() = 0;
+};
+
+}  // namespace blink

+#endif
