Exception(s) (if any)

We don't explicitly write out the JSON, we delegate it to Microsoft.OpenApi. That dependency was updated to the latest release (1.6.14) as part of the 6.6.x release (#2795), so I would have thought that if this is a bug, it should be logged there.

[DerGary]

Okay, is there anything that I need to do?

[martincostello]

I would suggest opening an issue in their repo.

Turns out it's now the expected behavior: #2268
