zh960 game piece icons in the hand disappear after flip board command

pkr5025 reported on Discord:
pretty minor issue, but when spectating zh960 on firefox, when I hit 'f' and flip the board, the piece icons in the hand disappear.
Before

After

refreshing brings the piece icons back, but also resets the board orientation

	style: {

pocket.style.setProperty('--piecerows', `${pieceRows}`);

Not sure where exactly it is controlled but when the board is flipped the --piecerows: 1 inline style disappears. Also, the issue affects all variants with pockets.
