Error on Starter Svelte App

[mattdesl]

Describe the bug

I just tried a simple svelte app (copying code from this folder) and it gives an error:

css-loader.js:30 Uncaught TypeError: Class constructor SvelteComponentDev cannot be invoked without 'new'

I am using parcel-bundler and parcel-plugin-svelte.

To Reproduce

npm init -y
npm i svelte parcel-bundler parcel-plugin-svelte

Then add the 3 source files from the earlier linked folder, and:

npx parcel index.html

Steps to Fix

To fix it you just need this in your package.json, which is not obvious and makes me think its a bug:

  ...
  "browserslist": [
    "last 1 chrome versions"
  ]
  ...

Versions

"devDependencies": {
    "parcel-bundler": "^1.12.4",
    "parcel-plugin-svelte": "^4.0.4",
    "svelte": "^3.12.1"
}
