I played a game against a druid who decided to give up. At that moment, I played a tortolan-piligrim, but as he surrendered, a pyroblast randomly got out which accidentally hit my face and the game ended in a draw. Previously, in this case, the discover menu was simply closing, but now this bug has begun to occur. This physically could not be a missklick since the pyroblast was located on the other side of the screen.
This is not actually exclusive to Discover. Any mid-sequence choice can be interrupted this way, and depending on the situation, the result may kill the player making the choice. In fact the easiest way to reproduce it is with Tracking and Ancient Curse:
This isn't particularly severe if the choosing player had only losing options like above, but it can happen when there are survivable options available, turning a win into a draw.
From the choosing player's perspective the full sequence is shown. From the conceding player's perspective, the opponent suddenly explodes alongside them with no explanation:

The log also has a full sequence for the conceding player, even though it does not animate:
