jQuery 1.5.1 event.js function: withinElement

jQuery 1.5.1 event.js function: withinElement

i get a lot of errors (ok only one ;) in the above function, when i look at the code i see

  1. // Firefox sometimes assigns relatedTarget a XUL element
  2. // which we cannot access the parentNode property of
  3. try {

when i am in development i want to stop on the try..catch...blocks, but only in my own scripts ;)

i found no ticket for this, so now my question: 

open a ticket? because problem is known
disable error tracking for try..catch is a must? is there an other way for me? :(
insert an   if (!parent) return;  on every version? :p   no i dont want that
you know the problem, but can't reproduce it? ok i can make a fiddle for you

thx in advice
