[jQuery] parents() clears vars

[Nikola Ivanov]

I have the following funtion:

function foo() {
  console.log( arguments ); // --> OK
  var e = arguments[0];
  console.log( e );                // --> OK
  var p = arguments[0].parents( 'li' ); // --> problem occurs ONLY if
this selection is empty
                                                          // and empty
selection is legit in my case
                                                          // same
behavior also when var p = e.parents( 'li' ) ;

  console.log( arguments ); // --> if p.empty --> [ ], else OK
  console.log( e );                // --> if p.empty --> [ ], else OK
  console.log( p );                // --> OK
}

What am I missing?

Thank you.
