Referees used to ignore unintentional fouls, like unintentional handballs, but it seems that with the introduction of VAR in this world cup, they're not ignoring anything.

For instance the penalty in France VS Croatia in World Cup 2018 final is an unintentional handball by Perišić. The referee had a hard time calling it, but he did.

So if a referee used VAR, is he still allowed to ignore unintentional fouls?
