Works perfectly, just need to refresh the page after opening it and it works (please fix at some point if you can).
For people who don't trust this, all you need to do is to change the "shorts/" to "watch?v=" but there is no need to do that for every video.

(For example:
https://www.youtube.com/shorts/Rn_DffYA_vM
Is a YouTube shorts link.
https://www.youtube.com/watch?v=Rn_DffYA_vM
Is the same video but as normal YouTube video and not shorts.
They both have the same ID, "Rn_DffYA_vM").
(I just picked a random video I found, but if you want the full video [because this is a shorts video and people usually don't tell from whom they took the source],
Matthew Weathers made it.)

I highly recommend this to every person who is using PC and doesn't want to keep dealing with the bad UI of YouTube shorts.
