I can replicate this. This is caused by the underlying yaml parser go-yaml.

For what it's worth - it's still valid yaml, it's just a formatting choice by the library. I'm guessing to split the entry so that they key is on one line 🤷🏼

See https://stackoverflow.com/questions/33987316/what-is-a-complex-mapping-key-in-yaml for more details. Feel free to raise an issue against go-yaml v3.
