Avoid escaping characters for custom templating values


When setting a custom templating, the values are escaped when used on an Elasticsearch data source.
If I set a custom template with this values: (A OR B),(C OR D) and then try to use them on a query like: field:$myTemplate
It ends up: field:\\(A\\ OR\\ B\\) What is not what I wanted, I wanted them literal.

Any idea?

There is an open feature request for disabling escaping, no ETA for when that will happen.

The same is for Prometheus data source. Grafana v7.5.17.

Do we have ETA when this will be fixed?
