Cannot find stdin on track modified using Snowpack

Trying out the new compiler with snowpack. Very minimal setup, with @snowpack/plugin-postcss added to the snowpack config and my postcss config looking like

module.exports = {
  plugins: {
    '@tailwindcss/jit': {},
    autoprefixer: {},
  }
};

Jusing the normal tailwindcss PostCSS plugin works just fine, but with JIT I am getting the following error on running yarn snowpack build:

[snowpack] ! building dependencies...

Hey all. @snowpack/plugin-postcss was updated last week and here’s how we recommend using Tailwind JIT with Snowpack:

1. Ensure that you are using the latest tailwindcss canary release (>= 2.2.0-canary.9): npm install -D tailwindcss@canary
2. Ensure that you are using the latest version of @snowpack/plugin-postcss (>= 1.4.0)
3. Set the TAILWIND_DISABLE_TOUCH environment variable to true. This enables an alternative watch method which is now compatible with @snowpack/plugin-postcss
4. Ensure that you are not using the devOptions.tailwindConfig Snowpack option

Here is a bare-bones example project: https://github.com/bradlc/jit-snowpack

If you are still having problems after following these instructions please open a new issue with a reproduction, thanks!

Theres a quickfix at https://github.com/snowpackjs/snowpack/commit/8ac85f6dff57ac49a9668dd5687d635ce054081d, where the full path is used instead of stdin, but there are still some problems in dev mode that are being worked on
