GetRoutingIDForWidget() doesn't always return the same routing ID for an
instance:
"""
This will take into account the current Flash fullscreen state, so if there is a
Flash fullscreen instance active, this will return the routing ID of the
fullscreen widget.
"""

I think you always want the routing ID of the render view hosting the plugin,
instead of the fullscreen render widget, right?

Changed to get the routing ID from the render view.

+  int routing_id = host_impl_->GetRoutingIDForWidget(instance);
   return ppapi::proxy::Connection(dummy_browser_channel_.get(),
-                                  plugin_to_host_router_.get());
+                                  plugin_to_host_router_.get(),
+                                  routing_id);
