Confirmed.

I assume the problem is caused by the missing end tag for the list,
since list is then not closed yet.

clone() will collect existing elements. appendTo() will then append
thoes elements. I did not have a look to the code of jquery, but i
assume clone() will also see those elements which get created by appendTo().

So this it what happens:

- clone() will fetch "Test1"
- appendTo() will create a copy of "Test1" and the end of the list
- clone() will fetch "Test2"
- appendTo() will create a copy of "Test2" and the end of the list
...
- clone() will fetch "Test6"
- appendTo() will create a copy of "Test6" and the end of the list

and NOW clone() will see the first copy of "Test1" since the list is not
closed by </ul> - therefore the whole process continues until the
browser crashes. Well - at least my FF 8.0.1 asks me after a while if i
want to stop the script ;-)
