I checked logs from the failed job and in fact this is duplicate of the neutron-ovs-agent crash issue https://bugs.launchpad.net/neutron/+bug/1944201
Routers aren't transitioned to "primary" because neutron-ovs-agent is dead in such job thus HA ports of the routers are DOWN. There is no neutron-l3-agent issue in that case at all.
I'm closing this bug as duplicate of the https://bugs.launchpad.net/neutron/+bug/1944201 and hopefully it will be fixed with new os-ken version.

Title:
  HA routers not going to be "primary" at all

Status in neutron:
  Confirmed

Bug description:
  It happens in the CI from time to time that many tests are failing
  because router is in backup state all the time and it's never
  transitioned to be primary on the node.

  Examples of the failure:
