Can't import i18next-browser-language-detector in SvelteKit (vite) using adapter-static

🐛 Bug Report

In my SvelteKit (using vite) project with adapter-static configured, I cannot build static files, because I get an error when importing i18next-browser-language-detector.

To Reproduce

3. install i18next-browser-language-detector and import anywhere with import LanguageDetector from 'i18next-browser-language-detector'
4. run npm run build to build static files

Expected behavior

No errors and success when running npm run build
