Grafana 11.3.0: Variable query using label_values(metric{label_filter}, label) not respecting label filter

### What happened? Hi team, I'm observing unexpected behavior while creating a variable in Grafana v11.3.0. Scenario: In Prometheus, I have the following metric: up{instance="svc-kafka1:9300", job="kafka_exporter", service="kafka"} Now, I want to create a variable in Grafana for instance, scoped only to the job="kafka_exporter". I’m using this query in the dashboard variable: label_values(up{job="kafka_exporter"}, instance) Issue: Even after adding the job="kafka_exporter" filter in the query, Grafana still returns all instance values across all jobs configured in prometheus.yml. It's as if the label filter is ignored. However, when I run the same query directly in Prometheus, it returns only the expected value: svc-kafka1:9300 ### What did you expect to happen? Expectation: Grafana should respect the label filter and only show the instance values where job="kafka_exporter". Please let me know if this is a regression or if there’s any additional setting required to enable proper filtering in variables. ### Did this work before?
