This is interesting as I had noticed this happening to me (in Chrome) when the anti-ad-blocking started. I assumed that it was YT's way of "annoying" me still while no ads were shown... It was eventually replaced with the "You cant use Adblockers modal" and now I just tolerate the ads.
So I wonder if that 5s delay has always been there.
