  The problem with attribute() is that with a long line and word wrapping enabled,
  when the long line is shown, it is called  as many times as the length of the line,
  in my test case, 566.039 times.
  
  The list is not always so small...In my test file, the longest list has 7257 items.
  Therefore, previously it had to go trough, in average,  3628 items 566.039 times.
  
  Kate and Okteta are the only tools that can handle such files and be responsive to user input.
