您好 我使用movable-area里面嵌套多个movable-view但是只有第一个能缩放？

   <movable-area style="height: 200px; width: 200px; background: pink;overflow: hidden;" scale-area>
    <movable-view bindchange="bindchange" style="width:100px;height:100px;background:#ccc;" direction="all"  scale scale-min="0.5" scale-max="10" scale-value="0.5">
    </movable-view>
        <movable-view bindchange="bindchange" style="width:100px;height:100px;background:#ccc;" direction="all"  scale scale-min="0.5" scale-max="10" scale-value="0.5">
    </movable-view>
  </movable-area>
