Vite-Node Import of '@js-temporal/polyfill' Is Undefined

[stolinski]

Describe the bug

Importing this package works fine with Vite, Node and other environments but comes in as undefined with Vite-node / Vitest.

optimizeDeps has no impact as well.

I looked through https://github.com/js-temporal/temporal-polyfill/blob/main/package.json but nothing stood out as being unusual, so I'm a bit lost as to why this import specifically fails.
