添加边之后在特定条件下，边的层级BUG

[lijiapeng0302]

Describe the bug

import { Graph } from '@antv/x6'

const graph = new Graph({
  container: document.getElementById('container'),
  grid: true,
  connecting: {
    anchor: 'nodeCenter',
    connectionPoint: 'anchor',
  }, //连线都在节点中心点
})

const source = graph.addNode({
  x: 120,
  y: 40,
  width: 100,
  height: 40,
  zIndex:10,
  attrs: {
    body: {
      fill: '#f5f5f5',
      stroke: '#d9d9d9',
    },
  },
})

const target = graph.addNode({
  x: 400,
  y: 260,
  width: 100,
  height: 40,
  zIndex:10,
  attrs: {
    body: {
      fill: '#f5f5f5',
      stroke: '#d9d9d9',
    },
  },
})

graph.addEdge({
  source,
  target,
  zIndex:9,
  connector: { name: 'smooth' },
  attrs: {
    line: {
      stroke: '#722ed1',
    },
  },

    tools: {
    name: 'vertices',
    args: {
      snapRadius: 2,
      attrs: {
        fill: '#444',
        r: 5, // 顶点的半径，控制大小
      },
    },
    }
})

上述为复现代码，当connecting: {
anchor: 'nodeCenter',
connectionPoint: 'anchor',
}, 属性连线都在节点中心点时，只要加入tools: {
name: 'vertices',
args: {
snapRadius: 2,
attrs: {
fill: '#444',
r: 5, // 顶点的半径，控制大小
},
},
}属性，不管边的zIndex设置为多少，鼠标移上节点，都能点击到边

Your Example Website or App

无

Steps to Reproduce the Bug or Issue

1、创建两个节点
2、用边连接两个节点，并设置节点zIndex>边的zIndex
3、鼠标移上节点

Expected behavior

当connecting: {
anchor: 'nodeCenter',
connectionPoint: 'anchor',
}, 属性连线都在节点中心点时，只要加入tools: {
name: 'vertices',
args: {
snapRadius: 2,
attrs: {
fill: '#444',
r: 5, // 顶点的半径，控制大小
},
},
}属性，不管边的zIndex设置为多少，鼠标移上节点，都能点击到边，正常期望结果应该为节点zIndex比边大的情况下，鼠标移上节点不应该能点击到边
