Passing :root as a selector?

Hi there I'm trying to pass a `:root` selector trough `astro-critters` unsuccessfully (so far). I have some dark mode settings set with `:root[data-theme~='dark']` and I'm trying to get those into the critical css. ```css :root[data-theme~='dark'] { --color-default: 128 0 29; --color-primary: 94 129 172; ... } ``` So far none of these seem to yield the desired result: ```js includeSelectors: [/\:root/, /^\:root.*/, /[:]\s*root.*/, /\:root\s*\{([^}]*)\}/, /\:root\[data-theme~=['"][^'"]*['"]\]/, /\:root/, ':root', ':root[data-theme~=\'dark\']'], } ``` By now I'm just throwing everything and seeing what sticks... Any ideas? cheers
