"hidden sm:block" does not work anymore with 4.13.

[magic-thomas]

Tailwind css 4.1.3 is used.

<div class="hidden sm:block">
      This should be seen only on desktop
  </div>

Always this code worked for me to show the contents on mobile device size.

But with tailwindcss 4.1.3 , it does not work for me any more.

Is it bug ?

Or is something changed ?

There is probably other CSS overriding this behavior. Do you have other CSS loaded with a .hidden class by any chance?

I was upgrading old project .. there was hidden style script which manually written.
