When certain core plugins have been disabled (eg. backgroundOpacity) tailwind-jit does not output alpha-less colors like tailwind does.

Is this is an intended breaking change or missing functionality? Happy to contribute if there is interest in supporting this use case.

Implementation difference:
tailwind-jit vs. tailwind

Example

With the following config:

module.exports = {
  corePlugins: {
    backgroundOpacity: false,
  },
}

Outcome:

.bg-gray-100{
	--tw-bg-opacity: 1;
	background-color: rgba(243, 244, 246, var(--tw-bg-opacity));
}

Expected outcome:

.bg-gray-100{
	background-color: #F3F4F6;
}
