Lines 142 to 145 in 780b7be

	let _ = komorebi_client::send_message(&komorebi_client::SocketMessage::MonitorWorkAreaOffset(
	model.index,
	komorebi_client::Rect { left: 0, top: height, right: 0, bottom: height }
	));

If a bar is destroyed either on purpose or program crash, we will have a weird gap at where the bar once was.

So set MonitorWorkAreaOffset to 0,0,0,0
