Your absolutely right to be stunned. The football lawmakers do not even understand the original concept of offside, not undertand the game from a footballers point of view, that they interpret last nights incident to be onside. The Spanish defence played a good line, so that Mbappe was in an offside position. The Spanish defender did the right thing in trying to cut out the forward pass, as he cannot of course be sure if Mbappe or any other French attacker times their run perfectly. Had the defender completely missed the ball, it would have been offside. But, as he got a slight touch, and deliberately tried to get a touch, then suddenly Mbappe is onside. It is crazy, ridiculous and shameful that the lawmakers get it so wrong. But, there you go, they seem to do that a lot.
