I'm getting this very regularly in my app as well. Any movement on this?

Edit: v2.2.0 (I only get this issue in production)

我也遇到这个问题，本地开发没问题，二级页面强制刷新就报错

I have similar issue with ElScrollbar component

@Spirit04eK @baixiaoyu2997 still not fixed, having the same issue with el-dialog. What's weird is that removing the parent

element fixes the issue.

Throwing error

    <el-popover>
      <div>
        <p>
          <span v-if="address"></span>
          <span v-else></span>
        </p>
      </div>
      <template #reference>test</template>
    </el-popover>

Working as expected

    <el-popover>
      <div>
          <span v-if="address"></span>
          <span v-else></span>
      </div>
      <template #reference>test</template>
    </el-popover>
