Research direction
Reproduce the issue by restarting TiFlash in a TiDB cluster and observe the Grafana store-size panel shown in the report. Trace the store-size metric from TiFlash startup to Grafana; done when the panel reports the real store size as soon as TiFlash starts rather than growing from zero.
