Updating to @rollup/[email protected] breaks svelte application

[rsheasby]

There seems to be an issue with the new es module reconstruction feature in 17.0.0 #537.

Everything was working without issue initially, but when I tried to upgrade my npm dependencies including this plugin to 17.0.0, I started getting the following error in my browser:

Uncaught ReferenceError: exports is not defined

When looking at my bundle, the Object.defineProperty(exports, "__esModule", statements are no longer being compiled away for some reason.

I'm unsure if this is a bug, or just a configuration problem relating to the new feature being enabled by default? If it is just a configuration change that needs to be made with the update, it's probably worth documenting this somewhere.
