youtube playlist embeds are sucking

This url: https://www.youtube.com/watch?v=HdMS19god0g&list=PL7E0DE3CF03D3E9B2&index=6

Makes an iframe with src: https://www.youtube-nocookie.com/embed/videoseries?list=PL7E0DE3CF03D3E9B2

So it is missing the index parameter. So video 6 doesn't play in the embed, video 1 does.

This iframe src url works, but having to subtract 1 in index? https://www.youtube-nocookie.com/embed/videoseries?list=PL7E0DE3CF03D3E9B2&index=5

On youtube, if you go to the original posted url, they tell you this is the embed. So maybe just drop the list and index parameters altogether.
