Reproducing the spread operator on a Set bug

1. in src/main.js on line 4, note the const uniqueValues = [...new Set([1, 1, 2, 3])]
2. run npm run build
3. in dist/assets/index-legacy[hash].js, inspect the traspiled code: [].concat(new Set([1, 1, 2, 3]))
4. the transpiled code evaluates to [Set(3)], but the source code evaluates to [1, 2, 3] in modern browsers
