Repeated notifications in case of datasource error

Hi, we configured a bunch of alert rules with "execErrState": "Error" setting.
When the problem with datasource occurs we don’t receive any notifications (as expected), but when the problem with datasource is gone we receive notifications for all the firing alert rules, even if we have already recieved them before. It looks like all the alerts are new, so there can be several repeated notifications for one problem.
Could you please tell me, is there a possibility to change this behaviour somehow to prevent duplicated notifications for the same problem?

Our grafana version is 9.1.6

Hi, any thoughts about this problem?
