 Hi Eric, I got the sequence in the if check right now, and indeed it makes
 much more sense now. I'm uploading a new patch, but the diff from the
 previous one is the following:
 {{{

              noParent = this.frame.parentNode !== this.layer.div,

              return undefined;
          }
 }}}
