Should we remove this function (and any tests using it)?

 {
-#if USE(GSTREAMER)
-    HTMLMediaElement* element = toMediaElement(node);
-    element->player()->simulateAudioInterruption();
-#else
     UNUSED_PARAM(node);
-#endif
 }
 #endif
 
 bool Internals::isSelectPopupVisible(Node* node)
 {
     if (!isHTMLSelectElement(node))
         return false;
 
     HTMLSelectElement* select = toHTMLSelectElement(node);
 
     RenderObject* renderer = select->renderer();
     if (!renderer->isMenuList())
         return false;
 
     RenderMenuList* menuList = toRenderMenuList(renderer);
     return menuList->popupIsVisible();
 }
 
 }
