        <pre>Bug is still present in 5.3.2.2. 

i tray quick if i can see something in the code. here the result.
i am not a Libre coder, i look in the code the first time and only for minutes.
i have not check the code logic! please a coder should check the conclusion
here carefully, and forgive me in case i searched at the wrong place...
if this is not the bug source, i will try to search a little more, to see how
far i come... but please check the argument here first.


this is the search trace so far
