Description

Hello.
It seems like the fix provided in https://github.com/codecentric/spring-boot-admin/issues/5286 is now preventing the UI to show the latest health state correctly and, instead, some stale value is getting shown.
See, for example, the picture below:

where the latest state is the one in the JSON on the right and it should, therefore, be DOWN, but the health indicator in the UI is still shown as UP.
Weird enough, the journal view doesn't show additional STATUS_UPDATED events either apart maybe the 1st one, whose payload matches the UI shown in the UI.
It's like the newer state is never produced by the SBA server, like if the StatusUpdater is stopped.
If it's not the case, then somehow the new states are not getting propagated, either in the back-end or in the UI.

Start with the StatusUpdater and the journal view, comparing the latest health JSON with the UI indicator and emitted STATUS_UPDATED events. Reproduce the setup with the WebFlux server, Servlet client, and Eureka discovery described in the issue. Done means a current DOWN state is produced, propagated, and displayed by the UI.
