Sorry, didn't mean for the PR to close this one when merging.

I fixed a related issue in IntelliSense itself but this will require a fix in Tailwind CSS itself to actually produce the completions. I've got a PR open for that here: tailwindlabs/tailwindcss#16353

This will be fixed in the next patch release of Tailwind CSS 👍

Gonna try to get the IntelliSense update itself out today or tomorrow too
