Dynamic row variable it's not well interpolated

Bug Report

When using Repeating Rows, based on a variable called $cloud_run_services which contain mulltiple values ['abc-api', 'xyz-api', 'aaa-api'], a panel inside one of this auto-generated rows the variable interpolated in the SQL query it's not well interpolated.

SQL query

SELECT
  timestamp,
  httpRequest.protocol,
  httpRequest.requestMethod,
  httpRequest.status,
  httpRequest.responseSize,
  httpRequest.latency,
  httpRequest.requestUrl
FROM
  carto-monitoring-gcp.cloud_native_log_sink.run_googleapis_com_requests
WHERE
  resource.labels.service_name = $accounts_cloud_run_services AND
  $__timeFilter(timestamp)

Expected Behavior

"SELECT
  timestamp,
  httpRequest.protocol,
  httpRequest.requestMethod,
  httpRequest.status,
  httpRequest.responseSize,
  httpRequest.latency,
  httpRequest.requestUrl
FROM
  carto-monitoring-gcp.cloud_native_log_sink.run_googleapis_com_requests
WHERE
  resource.labels.project_id = 'carto-acc-us-east1-1' AND
  resource.labels.service_name = 'abc-api' AND
  `timestamp` BETWEEN TIMESTAMP_MILLIS (1632384379085) AND TIMESTAMP_MILLIS (1632395179085)
 LIMIT 2126"

where abc-api is the value of the generated row out of the $cloud_run_services variable

This is the behavior for example in StackDriver data source

Actual Behavior

"SELECT
  timestamp,
  httpRequest.protocol,
  httpRequest.requestMethod,
  httpRequest.status,
  httpRequest.responseSize,
  httpRequest.latency,
  httpRequest.requestUrl
FROM
  carto-monitoring-gcp.cloud_native_log_sink.run_googleapis_com_requests
WHERE
  resource.labels.project_id = 'carto-acc-us-east1-1' AND
  resource.labels.service_name = 'abc-api', 'xyz-api', 'aaa-api' AND
  `timestamp` BETWEEN TIMESTAMP_MILLIS (1632384379085) AND TIMESTAMP_MILLIS (1632395179085)
 LIMIT 2126"

where 'abc-api', 'xyz-api', 'aaa-api' are the values of ALL generated rows out of $cloud_run_services variable

Steps to Reproduce the Problem

1. Create a new Grafana variable containing multiple values
2. Create Repeating Rows based on step 1 variable
3. Create a BigQuery query with a WHERE clause using the step 1 variable
