Wrong result when a selection is scoped using both the selector and the context param (or using find)

var parent = $("#parent");
$("#parent .child1, #parent .child2") => 2 elements = OK
$("#parent .child1, #parent .child2", parent) => 1 element ?
parent.find("#parent .child1, #parent .child2") => 1 element?
​ It should return 0 or 2 elements , but 1 element doesn't make sense. Reproduce on: ​http://jsfiddle.net/GRbHA/3/[[BR]]

I've reported this in Sizzle too: ​https://github.com/jquery/sizzle/issues/160

jQuery 1.8.x and edge find no elements with either $("#parent .child1, #parent .child2", parent) or parent.find("#parent .child1, #parent .child2").
