Describe the bug

Because of this, the color-text-700 class has no effect until I manually define the variable. I noticed that this only happens when using mode: 'shadow-dom'.

:host {
  --un-text-opacity: 100%;
}

My config:

export default defineConfig({
  presets: [
    presetWind4({
      preflights: {
        theme: {
          process: createRemToPxProcessor(),
        },
      },
    }),
  ],
})
