Spectate is broken

In any multiplayer ladder games, spectate is broken.
Whenever I attempt to spectate, it shows an extremely zoomed in corner of the arena.
Zooming in/out doesn’t help, whether using ctrl + or ctrl -, or by pressing the zoom in and out button provided by the site, it still shows a zoomed in corner of the arena…

Attached is an image of the broken spectate:

As you can see, the image is only showing the lower left-hand corner of Multiplayer Treasure Grove…
Something I did wrong?
Or is it a bug?

That is not a bug. It is just how the team formatted it.
