Good work on the PR!
Here's a possible optimization but otherwise LGTM:

switch (resolved.action) {
	case ActionType.Reduce:
	         let newOrder = [];
	         for (const idx of resolved.indices) {
		    if (idx === i) shouldIncrementI = false;
	            order[idx] = "";
		 }
		 for (const val of order) {
		     if (val != "") newOrder.push(val);
		 }
		 order = newOrder;
	         if (!shouldIncrementI) j = order.length; // Break out of inner loop
		 break;
	case ActionType.Nop:
		j++;
		break;
}
