version 7.0.0 `compilerOptions` breaks preprocess

This is the repo I’m using with tailwindcss and sapper-rollup template from https://github.com/andrasbacsai/sapper-tailwind-starter. I ran npm run dev and got this error:

Most people don’t include useless links in their report. “I’m using X … but not really”

You need to move the config keys into compilerOptions namespace inside your rollup.config.js file

svelte({
--  dev,
--  hydratable: true,
--  emitCss: true,
++ compilerOptions: {
++   dev,
++   hydratable: true,
++   emitCss: true,
++ },
  preprocess
}),

You have two of these – one in client and server options.

yeah I did that in the repo… also if I add emitCss: true, it doesn’t recognize it
