textarea 弹起速度缓慢

代码用的基本就是你们的示例代码，点击最下面的使得输入框获取焦点即可复现

<view class="page-body">
    <view class="page-section">
        <view class="page-section-title">输入区域高度自适应，不会出现滚动条</view>
        <view class="textarea-wrp">
            <textarea bindblur="bindTextAreaBlur" auto-height />
        </view>
    </view>


    <view class="page-section">
        <view class="page-section-title">这是一个可以自动聚焦的textarea</view>
        <view class="textarea-wrp">
            <textarea auto-focus="true" style="height: 3em" />
        </view>
    </view>
    <view class="section">
        <form bindsubmit="bindFormSubmit">
            <textarea placeholder="form 中的 textarea" name="textarea" />
            <button form-type="submit"> 提交 </button>
        </form>
    </view>
    <view class="section">
        <form bindsubmit="bindFormSubmit">
            <textarea placeholder="form 中的 textarea" name="textarea" />
            <button form-type="submit"> 提交 </button>
        </form>
    </view>
    <view class="section">
        <textarea placeholder="这个只有在按钮点击的时候才聚焦" focus="{{focus}}" />
        <view class="btn-area">
            <button bindtap="bindButtonTap">使得输入框获取焦点</button>
        </view>
    </view>
</view>

//textarea.js
Page({
  data: {
    height: 20,
    focus: false
  },
  bindButtonTap: function() {
    this.setData({
      focus: true
    })
  },
  bindTextAreaBlur: function(e) {
    console.log(e.detail.value)
  },
  bindFormSubmit: function(e) {
    console.log(e.detail.value.textarea)
  }
})
