Describe your issue

Color swatches are not displaying when referring to variables from the main config file. It worked fine with Tailwind v3.

main.css

    --color-test-500: #ff0000; 
    --color-primary-500: var(--color-indigo-50);

index.html

<div class="bg-text-500">Swatch displays</div>
<div class="bg-primary-500">Swatch doesn't displays</div>

The auto-suggest works fine however, it's just the color swatch
