thanks for the reminder. From a user point of view this issue hasn't 
been fixed so far. For our product we just reverted the commit in a 
downstream repo.

 From my understanding there was already an issue there and the 
optimizing commit by Tomasz just make the situation worse. Unfortunately 
my time budget to investigate this issue further is exhausted, so i 
stopped working at this.

In case someone can give clear instructions to investigate this further, 
i will try to look at it in my spare time. But i cannot make any promises.

Best regards
