plugins

When using ECMAScripts typeof on plugin elements (i.e. embed or object), Safari & FireFox return "function":

typeof(window.document['myPlugin']) // "function"

This can't be influenced on the plugin side, as the browser doesn't call the plugin here. Funny enough, in IE the same line evaluates to "object".

Is that simply implementation dependent behaviour as per ECMAScript §11.4.3 or am i missing something here?
