Will the escape be a problem, when we render it on https://developer.wordpress.org/block-editor/packages/packages-env/#wp-env-json ?

@Soean Can you give me a hint, how I can test this? I didn't found a way to generate the HTML docs.

Definitely looks better in GitHub. Thanks @simono! If it breaks wordpress.org then we should fix the parser that builds those docs pages.

@noisysocks Now the backslash is rendered in the handbook: https://developer.wordpress.org/block-editor/packages/packages-env/#wp-env-json

@noisysocks @Soean Thanks for the merge. Let me know if I can help to fix the backslashes in the handbook.

I created a ticket for the parsing issue in Meta Trac: https://meta.trac.wordpress.org/ticket/5123

This is the plugin that parses the markdown, if you'd like to try your hand at writing a patch to fix the issue: https://meta.trac.wordpress.org/browser/sites/trunk/wordpress.org/public_html/wp-content/plugins/wporg-markdown
