When a detail view for a alert is open, API request updating the request to OK fail

[peteeckel]

Issue Summary
When I have a detail view for an alert in state "Critical" open in the WebUI, events setting that alert to "OK" are processed, but the state does not change. Event etc. are set, but the state remains

Environment

• OS: Debian 12.7

• API version: alertad 9.0.4

• Deployment: self-hosted

• For self-hosted, WSGI environment: apache/gunicorn

• Database: Postgres

• Server config:
  Auth enabled? Yes
  Auth provider? LDAP
  Customer views? No

• web UI version: 8.7.0

• CLI version: 8.5.3

To Reproduce
Steps to reproduce the behavior:

1. Send a critical alert to Alerta
2. Open the "Detail" view in the WebUI
3. Send an OK alert to Alerta for the same resource, event etc. so that it is correlated
4. The state of the alert does not change to OK, but the remainder of the values of the "OK" alert are recorded properly.

If this should not be sufficient I'll need to set up a separate test environment for reproducing it reliably, as currently I only have the customer's production environment available.

Expected behavior
Same as above, but with the alert being updated to "OK" and closed.
