   @jherkel I stared at `TreeUtils#pathFor` and this method lacks documentation 
about the special cases it tries to cover. I agree that that the range checks 
are at least partially of from what I would expect, but then there is more 
black magic there.
   
   There would be huge risk in changing `pathFor`, so I looked at the core of 
the method and it is surprisingly simple. I came up with this:
   
   https://github.com/matthiasblaesing/netbeans/tree/pr-8834-2
   
   The idea here is to implement a simple TreePathScanner inline and use that 
to find the right TreePath. I added some more tests and them come out correctly.
   
   Would you please have a look?
