I had the same problem, now I use https://chrome.google.com/webstore/detail/stop-autoplay-for-youtube/lgdfnbpkmkkdhgidgcpdkgpdlfjcgnnh?hl=en-GB https://chrome.google.com/webstore/detail/stop-autoplay-for-... so that if I open a tab in the background I don't have to manually pause the Youtube video or I if restore a chrome session like you said.
