feat: remove un-cloak to html node as well as body

[vbrajon]

For one use case, I have an "un-cloak" attribute added automatically to the html tag dynamically before the body exist.
Plus I find this intuitive to have the attribute on the html tag, the fact that both work seems better to me.
Thanks for your work !

You can try here the following 2 links (to copy paste in URL):

data:text/html,

<style>[un-cloak]{display:none}</style> <script type="module"> import initUnocssRuntime from "https://patch.deno.dev/@unocss/runtime?dev"; initUnocssRuntime(); </script>

will show

data:text/html,

<style>[un-cloak]{display:none}</style> <script type="module"> import initUnocssRuntime from "https://esm.sh/@unocss/runtime?dev"; initUnocssRuntime(); </script>

will not show

The patch is available here: https://dash.deno.com/playground/patch

To check that this works as expected you can do:

document.documentElement.setAttribute('un-cloak', '')

In the preview playground, the runtime automatically delete it: https://deploy-preview-2026--unocss.netlify.app/play/
