remove(":nth-child(1)") works differently than filter(":nth-child(1)").remove()

[[email protected]…]

First, a jsFiddle example : ​http://jsfiddle.net/Jjym7/7/. In this jsFiddle, only the first child of each list should be removed.

According to the ​remove documentation, the remove method should do the same thing than applying first the filter method and then the remove method.

I think this is due to the fact that the remove function applies jQuery.filter in a loop for each element in the object so that each element becomes the first (:nth-child(1)) when the filter is called.

Line 5986 from ​http://code.jquery.com/jquery-1.9.1.js.

Agreed. It *seems* like moving the filter outside the loop and removing that set would be better anyway ... so it must be a trap of some kind.

Fix #13721. Filter before .remove() loop so positionals work. Close gh-1221.
