sorry, but the bug description is completely unclear to me

v8.0.0 is only compatible with newer browsers see changelog: https://github.com/i18next/i18next-browser-languageDetector/pull/286

if you need to support older browsers without transpilation, use v7

I'm really interested in how this is used as I would assume most people are using a build system to handle transpilation.

Could you share some insights into how you bundling your website?
