图案无法拖拽

图案无法拖拽，代码如下

const context = createCanvasContext("canvas");
const { screenWidth, screenHeight } = getSystemInfoSync();
const canvas = new wxDraw(context, 0, 0, screenWidth, screenHeight);
const rect = new Shape(
  "rect",
  { x: 60, y: 60, w: 40, h: 40, fillStyle: "#2FB8AC", rotate: Math.PI / 2 },
  "mix",
  true
);
canvas.add(rect);
