When using the 4k filter in Invidious, it doesn't filter by 4k.

Steps to Reproduce

1. Search for a video
2. select the 4k option and filter
3. four_k is added to the url, but it doesn't filter by 4k and the 4k option is now not selected in the filters
4. Change four_k in the url to 4k and it now filters correctly and shows the option selected Nvm it seems that the 4k option is fully broken
