I'm working on NativeWebKeyboard fix in separate CL and the code above and below
will be replaced with just

views::KeyEvent views_event(event.os_event);

+    views::KeyEvent views_event(
+        GetEventType(event),
+        static_cast<ui::KeyboardCode>(event.windowsKeyCode),
+        GetEventFlag(event));
+    focus_manager->OnKeyEvent(views_event);
+  }
+}
