The bug was imported by #3360

Without this fix, the test will fail (foo_milliseconds_total_total ):

Also related: #3360, since the regression seems to actually have been introduced there.

👋 any chance this fix can be back-ported onto a v0.33.1 release?

This is playing havoc with my metrics.

(I've moved to this merged commit above meanwhile - so not really blocked).

I expect the v0.34.0 release to land early next week. Hopefully that helps.
