Modal background not transparent anymore, because of tailwind 2 removed classes in tailwind 4

[Ukalus]

Describe the bug

bg-opacity- has been deprecated in Tailwind 3 and now completely removed in Tailwind 4.

could we update the Components to use opacity- instead?

workaround:

plugins: [
require("flowbite/plugin"),
plugin(function({ theme, matchUtilities }) {
const opacities = theme('opacity'); // Get the opacity theme values from Tailwind

  matchUtilities(
    {
      'bg-opacity': (value) => ({
        backgroundColor: `rgba(0, 0, 0, ${value})`, // Create the background color opacity utility
      }),
    },
    { values: opacities, type: 'value' } // Apply the values from the opacity theme
  );
}),

],

Reproduction

use Flowbite svelte with Tailwind 4
