Failed spectator connection resulted in false tournament victory

Title:

Summary:
Attempted to spectate someone, they were in Ranked.

Received Connection lost to Opponent error, before the match was able to be spectated, meanwhile the hold Y to stop watching prompt remained.

Spectator session never began after a few minutes of ‘waiting for next match’.

I hold Y and exit that attempt to spectate.

I go play Arcade instead, and at some point later, get pulled out of Arcade and then it transitions to showing me the tournament bracket with that player I attempted to spectate, shown as the winner. Then the scene transitions to displaying me as the winner and seeing the rank points accumulate. I acknowledge the result and it exits back to main menu.
