当我反对使用该控件进行旋转或缩放时，为什么它的位置也会改变，请参见下面的视频

我想在我当前的代码中得到以下视频结果
https://drive.google.com/file/d/1iy3216DTpsDREuXIvGG4JpD5iqRN-lQc/view
在旧的打包程序版本中它可以完美工作，但新版本无法工作
旧版本：“^0.96.0” 新版本：“^0.167.1”，
这是我的三个js环境设置代码

this.getMaterial();
if (this.activatedObject.name == 'text') {
this.getTextGeometry();
this.textEditor = true;
}
this.cancelHideTransorm();
}
这是我的旋转和缩放代码
getObjectPosition() {
console.log("object Position Changes");
