On my side, I don't do anything in the object template with SetCallAsFunctionHandler. I have tested setting my object template SetCallAsFunctionHandler and as you say, instant tooltip in DevTools shows the object as anonymous, but still prints as [object MyStuff] in the console. so I am afraid I can't be of any more help :(
