Summary NPN_InvokeDefault() on saved function() doesn't work.

I have a property on the object returned by NPP_GetValue(NPPVpluginScriptableNPObject) that the JavaScript in my HTML page sets to a function. I do an NPN_RetainObject() on what JavaScript passes to the property setting function but when I later try to call that function pointer with the NPN_InvokeDefault(<NPP that object was made with>, <saved function pointer>, NULL, 0, <an NPVariant>); it fails. And nothing is put in the JavaScript console about why it failed, so I have no idea what the problem is. I found a workaround, which is to call "call" using NPN_Invoke() on the function as the object and "call" as the method, which does work. But this case is what NPN_InvokeDefault() is for, so it should work.

Hi William, please test this against WebKit ToT (tip-of-tree) to find out if the bug still exists. A stand-alone test case (code and/or HTML) would also help to get this bug fixed quicker. Thanks! http://webkit.org/building/checkout.html
