In-game Spectator Bug

I was spectating my friend’s game once and switching between players’ POV doesn’t seem to properly work for some reason. If you try to switch to next player (with a left mouse click) it works as it should, but if you’re switching back (right mouse click) - game is just shutting down itself. Does everybody have this bug? My friend told me about the same issue and it seems like OW team is unaware of the problem.
