        * Temporary fix grafana-clickhouse-datasource as it requires the query editor to be fully rendered to update the query
        * Proposed fixes:
        * - https://github.com/grafana/clickhouse-datasource/issues/1363 - handle query update in data source
        * - https://github.com/grafana/grafana/issues/110868 - allow data links to provide meta info if the link can be handled in compact mode (default to false)
+       * Update:
+       * More data source may struggle with this setting: https://github.com/grafana/grafana/issues/112075
+       * We're making it enabled for tempo only and will try to make it optional for other data sources in the future.
