Jquery UI - 拖动旋转元素时出现问题

问题是，当我尝试拖动旋转的元素时，它会反弹...... 我无法找出元素上发生了什么。

如果元素未旋转，它将正确移动。我还在可拖动上使用"cursorAt"属性，但我仍然无法找出问题所在。

这是我的代码

$(function(){
    $('.obj-rect').resizable({
        handles:{
            'n': '.ui-resizable-n',  
            'e': '.ui-resizable-e',  
            's': '.ui-resizable-s',  
            'w': '.ui-resizable-w',  
            'ne': '.ui-resizable-ne',  
            'se': '.ui-resizable-se',  
            'sw': '.ui-resizable-sw',  
            'nw': '.ui-resizable-nw',  
        },
        alsoResize: ".textarea"
    }).draggable().rotatable();
});

/* Resizable Test */
.obj-rect{
    position: absolute;
    width: 120px;
    height: 80px;
    background: transparent;
    border: 1px solid #000;
}
.ui-resizable-handle{
    position: absolute;
    background-color: #fff;
    width: 8px;
    height: 8px;
    border: 1px solid #00a8ff;
}
.ui-resizable-helper { 
    border: 1px dotted #00F;
}
.ui-resizable-n{
    top: -9px;
    left: calc(50% - 9px);
}
.ui-resizable-e{
    right: -9px;
    top: calc(50% - 9px);
}
.ui-resizable-s{
    bottom: -9px;
    left: calc(50% - 9px);
}
.ui-resizable-w{
    top: calc(50% - 9px);
    left: -9px;
}
.ui-resizable-ne{
    top: -9px;
    right: -9px;
}
.ui-resizable-se{
    bottom: -9px;
    right: -9px;
}
.ui-resizable-nw{
    top: -9px;
    left: -9px;
}
.ui-resizable-sw{
    bottom: -9px;
    left: -9px;
}
.ui-rotatable-handle {
    background: url("https://cdn.jsdelivr.net/jquery.ui.rotatable/1.0.1/rotate.png");
    background-repeat: no-repeat;
    background-size: 100% 100%;
    height: 16px;
    width: 16px;
    position: absolute;
    top: -30px;
    left: calc(50% - 12px);
  }

这些用于原型工具，并在元素上使用"可拖动、可调整大小、可旋转">
