What do you expect to happen instead?
interface language should refresh the page and should stay on the current page
Steps to reproduce:

1. open https://peertube2.cpy.re/videos/watch/9c9de5e8-0a1e-484a-b099-e80766180a6d

2. click on change interface

3. select any language

4. you are thrown to https://peertube2.cpy.re/es-ES instead of the above link
