2005188 - (dt-@custom-media) [META] Add support for @custom-media in DevTools

Status: NEW

(DevTools :: Inspector: Rules, task)

Description

[Nicolas Chevobbe [:nchevobbe]]

From https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/At-rules/@custom-media

The @custom-media CSS at-rule defines aliases for long or complex media queries. Instead of repeating the same hardcoded <media-query-list> in multiple @media at-rules, it can be defined once in a @custom-media at-rule and referenced throughout the stylesheet whenever needed.

At the moment, the feature is behind the layout.css.custom-media.enabled pref

The Bugbug bot thinks this bug should belong to the 'DevTools::Inspector: Rules' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
