All PPPoE disconnecting after add or remove EoIP to Bridge

when i try to add or remove an EOIP interfaces to a Bridge, all the PPPoE tunnels (also the ones that belong to the others EOIP tunnels) keep disconnecting

RB1000
RouterOS 5.18

Please send this bug, along with supout file, to support@mikrotik.com

I think it is more simple:
the MAC-Adress of the Brdige is being altered to the MAC-Adresse of the EoIP-Interface.
This makes all PPPoE-Clients force to talk to another MAC-Adress, which causes them to drop the connection.

A simple precaution is to always set a Admin-MAC on bridges.
