API call /api/test/372/labelValues?limit=XYZ does not limit number of returned objects

[jhutar]

Describe the bug

Looking into https://horreum.hyperfoil.io/openapi/#tag/Test/operation/labelValues and looks like limit param limits number of labels returned at total across all returned object's values.

Normally limit limits number of returned objects.

Screenshot from Grafana for limit=1:

And limit=2:

And limit=90:

To Reproduce

Attempt to call that API with various limit values and observe number of returned objects
