In grafana/mimir#790 we've removed metric.Metric in favour of model.Metric. The next step could be just moving to labels.Labels in MetricsForLabelMatchers() instead of model.Metric. This could also save some memory allocations due to type casting.

Describe the bug
In Firefox, the zoom feature uses transform styles (see storybookjs/storybook#12845) - unfortunately this breaks positioning on elements that require position: fixed when in the "Docs" view.

Normally a position: fixed element's position would correspond to the viewport but in Firefox it corresponds to the element with the transform style.
