Twenty Twenty-One: Remove duplicate CSS rules.
Browse files Browse the repository at this point in the history 
Introduces a new PostCSS plugin, `postcss-discard-duplicates`, which will automatically remove any duplicate CSS rules. All the CSS that is removed shows up again later in the file. This also fixes a bug from `postcss-css-variables`, where media queries are duplicated.

Fixes #52158.
Props poena.
