No missing bricks in Google Chrome here, but i checked with Microsoft Edge and yeah they've gone missing. Weird, since it's just a 1:1 copypaste from http://tsk-tsk.net/net/temp/sarayan_dm-53.svg and honestly I don't know why, same for the missing top hose.
Both yours and this sarayan_dm-53.svg are missing the light brown bricks here in my Chrome. Strange your Chrome showing different results from mine.
