Playing as black against the chess.com computer, the following position was reached and chess.com declared checkmate in its favor. However, I don't see that the black king is in check. So is this a bug?
[FEN "2r2r2/p6k/2b1p1R1/2pp2Qp/P2P4/1PN5/1K6/8 b - - 0 1"]
There was no time limit in effect and this is the final position. There was a message that said "Checkmate" and I couldn't make any more moves. (White's last move was Qg5; it had been on h4.)
