Blocked site overriding whitelisted sites

[linka10]

I'm trying to use a regex line to make an exception for certain youtube pages that have playlists I use for concentrating. Here's an example of such a line:
https://www.youtube.com/watch?v=GrF2S2jSU2Y&list=PLmz5Tb_eNUFx_9P0UXwRTCNRWTCNcPmIU(&index=.)
Based on the editor you linked to, this should work fine. However, since I'm blocking youtube, I think that's overriding this regex statement.

Even without a regex, if I block youtube and use a normal string like https://www.youtube.com/watch?v=CMaGzdN8dvg&list=PLmz5Tb_eNUFz-WRI4Q9reSen2Y40LbjFw&index=1, it doesn't matter- as long as i'm blocking youtube, it will consider a whitelisted site from youtube as something to block.

Maybe I'm doing something wrong on my end and if I am please let me know, but I would think that if a certain page from a site is whitelisted, it should be overriding the block on the rest of the site.
