11 // It differs from the :hidden selector (jQuery.expr.pseudos.hidden) in two important ways:
12 // * A hidden ancestor does not force an element to be classified as hidden.
13 // * Being disconnected from the document does not force an element to be classified as hidden.

15 // detached or contained within hidden ancestors (gh-2404, gh-2863).
