AI Summary: Modify the link generation logic in Grafana's Explore and Dashboard panels to allow navigation to the Grafana Metrics Drilldown app even without a pre-selected metric in the query. This involves updating the link generation to always point to the root Metrics Drilldown view when a Prometheus data source is selected, regardless of the query's contents.

AI Summary: The task is to modify the Grafana Metrics Drilldown plugin to correctly identify native histograms when navigating to the metric scene from external applications. This involves updating the logic for identifying native histograms, likely by using the `MetricDatasourceHelper` and `isNativeHistogram` functions, to ensure that the correct visualization is applied regardless of the navigation source. The change should handle cases where the `nativeHistogram` variable is not present in the URL.
