test: Ensure private methods are visible from all initializers

This makes v8's _monkeyYaml happy --- without it, the info block never ends, and we fail to parse the `features` key.

An explicit indentation marker isn't used because monkeyYaml doesn't supported it, and adding it might slightly slow things down.

Using PyYAML instead was considered, but after trying it, I don't think it looks viable. [simple test cases](https://gist.github.com/caitp/4a59a67f671907c11051a1b7bd5fdaae)
