未能复现

@Leopoldthecoder 多操作几次看看。我这里不稳定复现，可能是偶数次操作才有？

[jerryWinhua]

@Leopoldthecoder @wacky6 兩位請嘗試這種方法 選取後再移出

[wacky6]

不是能很稳定的触发。
按住加号，往下移出组建范围（此时数字被选中）。然后重复这个动作。

感觉这个操作序列在实际中并不是那么容易出现？

加了个 @dragstart.prevent，应该是没问题了。

@Leopoldthecoder 感謝您，非常成功

thank a lot

加了个 @dragstart.prevent，应该是没问题了。

我这边加了在Safari浏览器下还是无效
