Can't play against computer

Trying to play a set-up position against computer gives this: abload.de/img/stockfishtakesanaptqk3h.png

No buttons to choose a color and start the game. :/

Happend on Firefox 78.0.1

@Dr_King_Schultz You can't play from position in under 1+0 controls

Oh, indeed! Thanks @learningchesskid3 !
