      Given a system is running the latest version of the OVN main branch and an environment set up to use ovn-fake-multinode for testing.

      When the periodic system tests is run which include scenarios with non-VIF ports, 

      Then, the ovn-controller should correctly process non-VIF ports incrementally without generating errors related to encapsulation.

      This bug is only present upstream, on the main branch, for now.  It was detected by the periodic system tests that use ovn-fake-multinode:

      https://github.com/ovn-org/ovn/actions/runs/9637361914/job/26576608290#step:17:52

      An example of the symptoms that cause the test to fail:

      Git bisect points to the following commit as the one that introduced this issue:

      Setting "severity: important" as this might cause issues once 24.09.0 is released and also because it makes upstream CI perma-fail.
