Shouldn't this be an object? Also, use value: function() { return {}; }.

Done.

I think it's better just to put the query call into the more-from-site handler
instead of firing this second event.

Hmmmmmmmm. I believe this equality is never true since menuIdentifier is always
created with a new item. You would need to implement your own
menuIdentifiersEqual() function to compare 2 menu identifiers.

I checked and if you click on the thin sliver of menu that is not obscured by
the menu, it doesn't close.
