Hi Leo,

Thanks for replying.
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 <rafael@rcpassos.me>"
tag would be nice, given the effort put into this.

Either way, thank you.
