Coin flip bug - The other side

I have noticed alot of people with very high mmr. I have tried going into the game but it is not working the same as everyone else.

What I have noticed while being on my computer, it has the cancel button that appears and disappears (as if joining into a game) and then the cancel button reappears. When I reloaded the client, it had boosted my MMR. I don't know how to give this information to the game creators/if it is useful for them. Obviously this post isn't to get people to abuse the bug.
