I can repro this with consistency in FF.
It seems that this only fires if you move focus from an element, to
something else and then immediately move to a child element of the first
element. If you go directly from the first element to the child, all is
fine.
A silly quick fix is to wrap this line in a try block
// Traverse up the tree
try{while ( p && p != this ) p =
p.parentNode;}catch(e){void(0)}

That is a weird one... let me know what you find out - did this bug
exist with 1.0 & autocomplete?
