• fix unescaped url params (such as & in the song artist)

  fix [Bug]: Genius lyrics incorrect #1050

---

• add slight delay to lyrics genius

  this allows YouTube to finish doing what it needs (removing native lyrics / updating with new native ones)

  fix Lyrics from previous song remain when skipping #1041 and other lyrics issues

  instead of a 500ms timeout, it could setup an observer. but I think it's unreliable since sometimes youtube might have done it's job before the observer would be set up - and right now I don't have a better way to check if the job was done

I love 3 lines changes that fixes alot of bugs 😋

I'll update these in my pr as well

Works; lyrics label also undims itself on its own without having to click on other parts of the menu

nit: could be a file const
