Thanks for the fix. I'm a bit confused as to why mockery is doing this in the first place but regardless it seems like this will work. Will merge once the checks pass.

Look like github.com/vektra/mockery/v2/pkg/fixtures/12345678/http was not actually included in this PR?

Yeah, me too. Feels like just adding a digit at the end would be enough. But I thought this fix was least intrusive as it won't change the existing behaviour 😅
