This is done by adding the scriptable plug-in's JS object to the
prototype chain of the element's JS object. See
nsHTMLPluginObjElementSH::SetupProtoChain in nsDOMClassInfo.cpp.
nsCOMPtr<nsIMyPlugin> myplugin = do_QueryInterface(elem, &rv);
In the last line I can't query the interface. The return value rv is
0x80004002 (NS_NOINTERFACE). But the interface is there, since it is
callable from java-script.
Not at all. The interface is in fact not there on the element itself.
