Public bug reported:

The Logical_Switch_Port.up event that sets the value to [True] is missed by Neutron API. For example, from [1]:
* Neutron port ID: 5dfa3f4d-7d89-4311-94a1-b7dfc5585cc5
* Logical_Switch_Port:
* Port_Binding: 470f5a71-c098-4e7f-8696-a153c02ce519

(1)
 The Port_Binding is set to UP when the port is created in the local OVS [2]:
{"_date":1736480121340,"_is_diff":true,"Port_Binding":{"3a63db7e-2314-4e2e-8ce6-9410d15558eb":{"up":true}},"_comment":"ovn-controller"}

This event is received by the Neutron API:

This event is NOT received by the Neutron API.


There are many examples of this behaviour in the CI logs.
