DSA and Multicasts switching

Hello. Is there a reason, to not forward multicasts (STP, LACP) trough DSA on Clearfog Pro? (kernel 5.15.110)

The router says, packets are outgoing off the eth1 (tcpdump says so) interface
20:02:22.203579 STP 802.1w, Rapid STP, Flags [Learn, Forward], bridge-id 0000.2c:23:3a:a2:be:3b.8003, length 36

dsa interface
20:03:10.201979 EDSA 0xdada, Forward port 1.0, VLAN 4095u, STP 802.1w, Rapid STP, Flags [Learn, Forward], bridge-id 0000.2c:23:3a:a2:be:3b.8003, length 36

but there in nothing on the "receiver" to see (tcpdump on the receiver says so) and.

The same configuration with clearfog base works well

One more edit:
I need to create transparent L2 pipe between two remote sites. Im using ip l2tp, patched bridge to enable change group_fwd_mask (this works. received multicast is forwared to the other site but is not outgoing off the interface)
