[v4] Angular conditional class not recognized by tailwind

Reproduction URL

I made a small repository showcasing the bug: https://github.com/Eirmas/tailwind-4-bug

Describe your issue

Angular allows for adding conditional classes with the following syntax:

<div [class.pt-4]="bool"></div>

It seems that Tailwind doesn't see the pt-4 class being used here, and therefore doesn't add it to the stylesheet.

This was working on v3 as I can recall

This will be fixed in the next patch release of Tailwind CSS. Thanks! ✨
