Alert: labels missing for query results with named columns

[k-meister]

What happened:
Hi guys!
When creating an Alert Rule on Clickhouse datasource, you get series named after query only.
Column names given in the query itself is missing completely.

Screenshots:

Why is it important
It's common for us to select for multiple metrics in one query.
Having this problem, alert rule fires with just "Value" in payload, instead of the name of the metric.
Thus, engineers have to browse to dashboard panel and do a research on which metric has gone wrong.

What you expected to happen:
Series' labels to contain names given in SELECT clause.

How to reproduce it (as minimally and precisely as possible):
Just make a query as on the first screenshot.

Anything else we need to know?:
On a dashboard panel, this thing seems to work fine, it's an alert rule that's affected.

Environment:

• Grafana version: Any 11.2+ (at least)
• Plugin version: 4.3.2
• OS Grafana is installed on: Dont know
• User OS & Browser: Any

It appears the alises are provided correctly in the query, not sure why only E is showing for both lines in your screenshot.

Perhaps the Grafana team has some ideas? @bossinc
