Have you read the rules?

They don't say anything about it, apart from...

"If a defending player steps behind his own goal line in order to place
an opponent in an offside position, the referee shall allow play to
continue and caution the defender for deliberately leaving the fi eld
of play without the referee’s permission when the ball is next out of
play."
