map组件的controls无法显示  使用cover-image虽然显示，但是不如map层级高 基础库2.12.2 ,下面是部分代码

<template>

  <view class="addrContent">

    <map

      style="width: 100%;"

      :style="'height:' + windowHeight * 2 + 'rpx'"

      :latitude="latitude"

      :longitude="longitude"

      :markers="covers"

      :polyline="polyline"

      :controls="controls"

    >

      <cover-view class="outTickrt">

        <cover-image

          :src="$url + '/4-1.png'"

          class="E-ticket"

          @click="buyTicket"

        ></cover-image>

      </cover-view>

    </map>

  </view>

</template>

controls: [

        {

          id: 1,

          iconPath: "../../static/icon/4-1.png",

          position: {

            top: 50,

            width: 100,

            left: 10,

            height: 100,

          },

          clickable: true,

        },

      ],
