threejs中group下绑定唯一key导致parten丢失的问题

技术架构

• react
• threejs
• @react-three/drei
• @react-three/fiber
• @use-gesture/react

场景

一个分组下有一个Line，当使用gesture的useDrag触发事件以后：

import { Line } from '@react-three/drei'
import { ThreeEvent, useFrame } from '@react-three/fiber'
import { useDrag } from '@use-gesture/react'
import { useEffect, useState } from 'react'
import { DoubleSide, Vector3 } from 'three'

const lineWidth = 4
const LinePropsData = {
  color: 0x3b61fa,
  lineWidth: lineWidth,
  dashSize: lineWidth,
  gapSize: lineWidth,
  side: DoubleSide,
}

/**
 * 区域入参定义
 */
export interface ExampleProps {
  positions?: Vector3[]
}

const Example: React.FC<ExampleProps> = (props) => {
  const { positions = [] } = props
  const [linePositions, setLinePositions] = useState<Vector3[]>([...positions])
  useEffect(() => {
    if (!positions) {
      return
    }

    setLineP
