Oh, they did similar for Columbus. Farsi was actually injured in the box, but at first they were convinced he was somehow offside despite having, like, a meter of space. (The phantom offside took place at the center line. Yes, it took them that long to come up with a wrong call.) VAR initially backed the folks on the field, but while the trainer was out working on Farsi they apparently decided to take a second look and thankfully got it right.
Of course, then Guzan manages to save it, but, meh, we won regardless so it worked out in the end.
