I don’t fully understand this:

Bridge VLAN Filtering since RouterOS v6.41 provides VLAN aware Layer2 forwarding and VLAN tag modifications within the bridge. This set of features makes bridge operation more like a traditional Ethernet switch and allows to overcome Spanning Tree compatibility issues compared to the configuration when VLAN interfaces are bridged.

What means that(?):

makes bridge operation more like a traditional Ethernet switch

How it exacly works without enabling VLAN Filtering in bridge?

When VLAN filtering is not enabled on the bridge it behaves like an unmanaged switch - packets with any ethertype, including 802.1Q VLANs, are forwarded to all* ports.

(* - based on the usual learnt MAC address forwarding table)
