Opening a video on YouTube creates new tiles

Opening a video on YouTube creates new tiles and changes to FavIcon.

I don't know if this is a bug really, as each new accessed URL should have its own tile, no matter if they share the same origin.

/cc @bbondy @bsclifton for better thoughts.

About favicon thing, that's a known issue #5310, where we collect this data later than expected.

@cezaraugusto in that case browsing 9 different URL of the same origin fills up all the tiles. I feel each tile should be blocked for an origin and not the visited URL's. If you Google search for 10 different items then it will fill all the 9 tiles, which doesn't make sense, putting Google on one tile makes sense because the site is visited frequently(10 times). This would precisely make it as a top site and adding it as a tile makes sense.

I'm going to mark this as a dupe for now- I think it's a great concern though. Let's chat in #5338
