Describe the bug
For a given histogram metric, exemplars disappear if metrics generator is switched from classic histograms to native histograms.
Additional Context
Looking at the original native histograms PR, exemplars should be supported. #3789
But it looks like they got hardcoded to be disabled by a chore commit dbd7505.
