Stay on the current page when changing interface language

[Pikachuzzz]

What happened?
When we change the language on a page of a video, we are sent back to the homepage
What do you expect to happen instead?
I think it would be better to stay on the same page when changing the language
Steps to reproduce:

1. Go on a video page

2. On the left, change the language

changing theme in any page just closes the modal and the setting is changed but language change always defaults to homepage. this should be fixed
