ES snapshot metrics don't respect grafana defined variables

[KyriosGN0]

Bug Report

What did you do?
tried to create alert for problems in ElasticSearch Snapshot
using the metrics "elasticsearch_snapshot_stats_latest_snapshot_timestamp_seconds" for example
we define a cluster variable in our grafana dashboard based on "elasticsearch_cluster_health_status"
but for snapshot related metrics that variable doesn't get those values, instead it only get values from the datasource.

What did you expect to see?

snapshot metrics uses cluster labels like other merics

What did you see instead? Under which circumstances?
snapshot metrics uses cluster labels from datasource instead of grafana
