We missed that patch, since there is no reference to the report. I understand the implementation ended up differently, and our patch is not going forward. But at least we came to the same conclusions. :) If I could ask, at least a "Reported-by: Rafael Passos " tag would be nice, given the effort put into this. Either way, thank you. - Rafael Passos
