[BUG] Per Bucket Monitor History bar remains green with active alerts in particular conditions

[thmsbp]

What is the bug?
Per Bucket Monitor History bar remains green with active alerts in particular conditions.
The visualization is this one (from Opensearch playground platform)
https://playground.opensearch.org/app/alerting#/monitors/yDYZA5MBUtEtjXPzRt-E?alertState=ALL&dataSourceId=&from=0&monitorIds=yDYZA5MBUtEtjXPzRt-E&monitorType=cluster_metrics_monitor&search=&severityLevel=ALL&size=20&sortDirection=desc&sortField=start_time

When an alert is triggered the first time, the red bar appears in the Monitor history.
On a second execution of the Monitor query, the alert is triggered again as depuped (not new anymore)

With no "throttle" defined, it may trigger a lot of deduped alerts every minute.

When the issue is terminated/complete, the red part disappears from monitoring history bar.
More commonly, if the user check this history 5min after a solved issue, the issue is not present in the history bar.

How can one reproduce the bug?

• Create a "per bucket" monitor
• With a query every 2min
• Have test data to trigger the alert
• Set test data to trigger the alert
• Check the monitor history (red part should be visible)
• Wait 4min (deduped alerts are generated)
• Set test data to not have the alert anymore
• Wait 2min
• Check the monitor history (red part is not visible anymore = bug)
