Describe the bug
using ^3.7.4
I get the this message when building for production:
"Named export 'IntlMessageFormat' not found. The requested module 'intl-messageformat' is a CommonJS module, which may not support all module.exports as named exports."

To Reproduce
In whatever repo using svelte-i18n, run npm run build and npm run preview

I fixed the problem by installing intl-messageformat in my project ^10.5.1
