Piglins will attack wither skeletons on the same team when friendly fire is set to false.

Creating a team and setting friendlyfire to false will not prevent a piglin from attacking a wither skeleton when both are part of said team, yet the wither skeleton will not attack the piglin.

The bug can easily be reproduced by creating a team, setting friendly fire to false and summoning a piglin and a wither skeleton that are on the same team nexto to one another.
