Description

This is a proposal to add some features to both CSS and HTML (and additional precision to HTML) to make the details and summary elements more easily styleable by authors.

Making these elements better stylable makes a lot of sense. I suggest we resolve this as "position: support" one week from now.

I left these comments in the course of my review:

::details-content vs display: contents might make them hard to remember, but that's probably a lost cause.
If the text is generated by the user agent, it should probably adhere to the language of the node rather than the end user's chosen language. But that's an existing issue and can be follow-up.
