[Bug]: Custom edges obscure nodes #6692

Describe the bug / 问题描述

参考文档的自定义边 https://g6.antv.antgroup.com/manual/custom-extension/element#%E8%87%AA%E5%AE%9A%E4%B9%89%E8%8A%82%E7%82%B9， 进行自定义边后，在开启drag-element、click-select、brush-select三个事件后，拖拽节点再点击画板会导致边的盖住节点

import { BaseEdge, ExtensionCategory, Graph, register } from "@antv/g6";

class ExtendBaseEdge extends BaseEdge {
  // 重写 getKeyStyle 方法
  getKeyStyle(attributes) {
    return { ...super.getKeyStyle(attributes), lineWidth: 2, stroke: "#000" };
  }

  // 实现 getKeyPath 方法
  getKeyPath(attributes) {
    const { sourceNode, targetNode } = this;
    const [x1, y1] = sourceNode.getPosition();
    const [x2, y2] = targetNode.getPosition();

    return [
      ["M", x1, y1],
      ["L", x2, y2],
    ];
  }
}
register(ExtensionCategory.EDGE, "custom-polyline", ExtendBaseEdge);
