Looks like this patch was reverted in Linus's tree:
d2e381c4963663bca6f30c3b996fa4dbafe8fcb5 (rtnetlink: Fix regression in
bridge VLAN configuration)
Also after some investigation I think my problem was actually with
NetworkManager as systemd-networkd + systemd-resolved works fine.
$ grep ^dns /etc/NetworkManager/NetworkManager.conf
dns=systemd-resolved
with this patch:
$ resolvectl
