Health Events With No End Date

[egauk]

Some health events never provide an end date or closure event. We are having a difficult time determining when an event has ended or closed. What logic does the AWS Health Dashboard use for events without a provided end date, closure event, or status? It looks like it may use Last update time.

Example Events
RDS operational notification
OpenSearchService service software update available
VPN redundancy loss

*I see a new EventBridge schema for [aha-2.1-beta] and it looks like this may be solvable in that release.
