Attaching custom tags workflow metrics

Community Support

After configuring PrometheusMeterRegistry

I see below metrics

temporal_poller_start_total{Namespace="mynamespace",TaskQueue="MyQ",} 8.0
temporal_workflow_task_replay_latency_seconds_count{Namespace="mynamespace",TaskQueue="MyQ",WorkflowType="Sample1",} 3.0

but i see an additional comma and the custom tags are still missing.
Is this same as what is being discussed in a similar thread @manu ?
