Add oEmbed functionality to handbooks

[dd32]

As reported in ​https://github.com/WordPress/gutenberg/issues/13001 oEmbed for handbook content doesn't work as expected.

I'm unsure why it's not being handled correctly, I suspect it's a query reset or something somewhere..

If it was working, ​this url would look similar to ​this one which is a generic empty oEmbed.

The Example URL ​https://developer.wordpress.org/themes/functionality/sidebars/ is the one that didn't work.

Oddly enough the ​Gutenberg Handbook does though which might mean it's in the Dev theme and not the handbooks code?

Gutenberg Docs: Don't add the Github edit link on oEmbed views.

This fixes having 2 super-large octocats appear in the oEmbed preview when embedding links to the Gutenberg Handbook in WordPress pages.

Is this also causing the formatting issues on ​https://developer.wordpress.org/plugins/the-basics/header-requirements/ ? I know this page was recently edited and was not exhibiting these formatting issues previously.

See ​https://cshp.co/2EDtL6x for screenshot example.

The formatting issues are a separate problem. I've fixed the article you linked by converting it to blocks and then converting the previously shortcode-wrapped code to instead live in a Syntax Highlighted Code block.

Awesome, thanks! Looks much better now.

Handbooks: Don't override the embed.php template, and don't prefix the TOC to the embed previews.

Fixes #4013.
