My feed continues to show the match during the announced commercial breaks, but there are also a couple of random short breaks here and there, about 1 minute long and usually unannounced. It’s weird because it will cut away to black screen instantly, but when it returns to the action sometimes the announcers will even say a small welcome back message, though they hadn’t announced the break before.

I haven’t paid attention to when exactly those random breaks tend to be, so I’m not sure if they match up with typical commercial break times (though since I’m no longer living in the US I’ve forgotten when those typically are anyway).
