Pending period in the Grafana UI is bound to the wrong value

[Fresa]

It seems pending period is bound to the evaluation interval when the UI for an alert rule is loaded even if there is a custom pending period defined. In the following example an evaluation group has been assigned with the Evaluation interval of 1m. A pending period of 30m has been configured, incorrectly visualized as 1m. If you look in the edit evaluation group modal you can see the rule having a pending period of 30m. If I save the rule now the pending period will become 1m.
