OpenAPI 3.0 Callback malformed rendering

Describe the bug OpenAPI 3.0 callback fields do not get rendered correctly in the .md output. There are a few issues:

• I think the main issue is that the ## heading is duplicated for each request, even if there’s only one request with a callback. This may be triggering the secondary issues. Please see the attached screenshot of Shins loading the .md file.
• The API call is duplicated in the center column.
• The code block is rendered within the center column.

• - I have checked that my input document is valid OpenAPI 2.0/3.0.x or AsyncAPI 1.x

To Reproduce Steps to reproduce the behavior:

1. For the input file, use the callback-example.md from the official OpenAPI repo’s 3.0 example spec: https://github.com/OAI/OpenAPI-Specification/blob/master/examples/v3.0/callback-example.yaml
2. Command-line:

node widdershins callback-example.yaml -o callback-example.md

1. Load callback-example.md from shins.
2. See layout errors in screenshot.

Expected behavior I’d expect:

• To see a single entry in the TOC for post__streams.
• To see a single entry in the enter column for post_stream.
• To not see example code in the center column.

Thanks for digging further. I believe it was working when released, possibly the overrides css in shins is required.

Any update on this? also happy to test it out
