The delay also does not trigger just once; it is reportedly triggered every time YouTube links are opened in a new tab.
This part got me yesterday as I was listening to music. I loaded a new video in a tab and the other tab waited 5 seconds. I thought I had paused it or something but nope, every time you load a new tab it delays all the other tabs by 5 seconds.
Deep Space 9 just got new holoemitters I guess.
