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.
