VLAN filtering broken in kernel 5.15.x (hbl)

In my setup, Mox acts both as a router for some vlans as well as a switch for others. I put all ports including eth0 into one bridge and use vlan filtering.

config device
        option name 'br-lan'
        option type 'bridge'
        option bridge_empty '1'
        option force_link '1'
        list ports 'lan1'
        list ports 'lan2'
        list ports 'lan3'
        list ports 'lan4'
        list ports 'eth0'

config bridge-vlan
        option device 'br-lan'
        option vlan '22'
        list ports 'lan3'
        list ports 'lan4'

config bridge-vlan
        option device 'br-lan'
        option vlan '60'
        list ports 'eth0:t'
        list ports 'lan1'

config bridge-vlan
        option device 'br-lan'
        option vlan '62'
        list ports 'lan2'

config bridge-vlan
        option device 'br-lan'
        option vlan '20'
        list ports 'eth0'

config bridge-vlan
        option device 'br-lan'
        option vlan '21'
        list ports 'eth0:t'

config interface 'wan'
        option device 'br-lan.20'
        …

config interface 'lan'
        option device 'br-lan.22'
        …

# uname -r

After upgrade to kernel 5.15.50 in HBL, I am having troubles with VLAN 60, that just traverses tagged on eth0 and untagged on lan1 port. The ingress traffic on lan1 gets tagged and delivered to eth0 but in egress direction, the tag is not stripped when leaving lan1 interface despite bridge vlan show showing Egress Untagged. There are no problems with other VLANs which don't traverse between ethernet ports. Alo if I use different LAN port in place of eth0 for uplink, problem is gone.
