DNS doesn't work until restarting systemd-networkd

After booting, I have an IP and internet access (through a home router), but no DNS resolving. I use systemd-networkd, and I have systemd-resolved set up in the stub mode. The network conf is set to use DHCP. I have an ethernet device (enp5s0) and a bridge (br0) set up with the typical configuration in the wiki.

Restarting systemd-networkd makes everything work fine. This started happening yesterday with no system configuration changes. The only potentially relevant previous package updates were systemd, systemd-libs, device-mapper. Systemd is version 242.0-1. systemd-resolveconf is not installed. device-mapper is 2.02.184-4.

When broken, output of resolvectl shows "Current Scopes: none" for the bridge, and no DNS servers. After networkd restart, scopes are "DNS LLMNR/IPv4 LLMNR/IPv6".

Setting the networkd unit to use debug mode shows some seemingly relevant info and differences. This is the journalctl output during the initial boot:

And this is it when restarting it, which shows no such issues:

Re: DNS doesn't work until restarting systemd-networkd

If you revert the systemd 242 update from the testing repositories does the issue cease to occur?
If so please check if the issues has already been reported upstream at [1] if not please bisect systemd between 241.93 and 242
then report the issue upstream then report the issue on the arch bug tracker to prevent the packages being moved from testing.

Re: DNS doesn't work until restarting systemd-networkd

Thanks. I've created:
https://github.com/systemd/systemd/issues/12315
https://bugs.archlinux.org/task/62347

Downgrading systemd does make the issue disappear, and so does removing the bridge, but there are some inconsistencies (242 occasionally behaves even with the bridge).
