Lose a game after 19 seconds without a move

I started this game, lichess.org/wZlmGh2GaVeQ, made a move as white, got some trouble with my mouse, fixed it and made another move (kf3), then the move is reversed and I lose for leaving the game. After 19 seconds, on a 5 minute game! What happened here?

i think that if u leave the game,u lose automatically.im not sure

I don't think I have left the game. While I was cleaning the mouse the confirmation box for leaving the game appeared but no button was pressed. Even if that was the reason, 19 seconds is a way to short time period for a 5 minute game. Browsers can crash or get stuck. I have had to wait for minutes after opponents disconnect for the game to end.

Perhaps a glitch?
