Found a bug in live chess system of chess.com. In a game I was watching here: https://www.chess.com/analysis/game/live/4919036363, this position arised and the black player ran out of time but the game was ruled a draw by chess.com. The white player should have been awarded the win as a mating position is still legally possible.

Under the FIDE laws of chess, this game should be ruled a win for white.
