Vite production bundling issue

[dysfunc]

Describe the bug When building a production bundle using vite build, the @shopify/prettier-plugin-liquid creates an exception:

RollupError: Identifier "x" has already been declared
    at error (file:///Library/WebServer/Documents/opensense/node_modules/rollup/dist/es/shared/parseAst.js:337:30)

I've created a sample app using stackblitz that reproduces the issue. https://stackblitz.com/edit/vitejs-vite-xivzdt?file=src%2FApp.svelte.

If you run npm run dev, it will compile and work as expected. When you run npm run build, it will try to compile but eventually throws an exception for Identifier "x" has already been declared. I've isolated this issue to this package. If I comment out this package and its usage, my production builds succeed.

Hey @dysfunc, Thanks for raising this - I Just wanted to confirm whether this is still an issue!
