Your configuration
/interface bridge
add > frame-types=admit-only-vlan-tagged > ingress-filtering=yes name=bridge1
protocol-mode=none vlan-filtering=yes
says bridge interface is tagged. Period. And that’s true for any VLAN, untagged frames are blocked on ingress on this interface. Bolded property setting annihilates any PVID setting on bridge interface (default setting is PVID=1, explicit setting wouldn’t matter either in this case). For egress it’s possible to set bridge interface to be untagged nember of multiple VLANs, but net effect will still be no bi-directional traffic of untagged frames through bridge interface.

The quoted config stanza is not about bridge - the switch like entity -, it’s about bridge interface. And doesn’t affect the rest of bridge ports in any way.
