What did you do?

I performed the following queries:

series_with_exponential_native_histograms + series_with_custom_buckets_native_histograms

series_with_custom_buckets_native_histograms_layout_1 + series_with_custom_buckets_native_histograms_layout_2

As the names suggest, these series contained native histograms with exponential and custom buckets.

What did you expect to see?

Warnings that either include the appropriate metric names, or don't mention metric names at all.

For example, the first case could return a warning like PromQL warning: vector contains a mix of histograms with exponential and custom buckets schemas for binary operation (1:1).

What did you see instead? Under which circumstances?

The first query result included the warning PromQL warning: vector contains a mix of histograms with exponential and custom buckets schemas for metric name "" (1:1).

The second query result included the warning PromQL warning: vector contains histograms with incompatible custom buckets for metric name "" (1:1).
