When combining TailwindCSS with AntD, the TailwindCSS intellicense stops working

Intellicense does not work:

@layer theme, base, antd, components, utilities;
@import "tailwindcss";

Intellicense works:
@import "tailwindcss";

This issue occurs in TailwindCSS v4

Whenever I define custom theme props in Tailwind CSS, they are also not working.

My wxt.config.ts

import { defineConfig } from "wxt";
import tailwindcss from "@tailwindcss/vite";
import path from "path";
// See https://wxt.dev/api/config.html
export default defineConfig({
	modules: ["@wxt-dev/module-react", "@wxt-dev/auto-icons"],
	autoIcons: {
		baseIconPath: "assets/icon.png",
	},
	vite: (configEnv: { mode: string }) => ({
		plugins: [tailwindcss()],
		resolve: {
			alias: {
				"@": path.resolve(__dirname),
			},
		},
	}),
	manifest: {
		permissions: ["storage"],
		author: {
			email: "[email protected]",
		},
	},
});

tailwind.config.ts

import { fontFamily } from "tailwindcss/defaultTheme";

/** @type {import('tailwindcss').Config} */
export default {
	darkMode: "class",
	prefix: "",
	content: ["./entrypoints/**/*.{html,ts,tsx}", "./components/**/*.{ts,tsx}"],
	theme: {
		extend: {
			fontFamily: {
				title: ["'Poppins'", ...fontFamily.sans],
			},
		},
	},
	plugins: [],
};
