image或者selection的限制边界在接近边界时卡顿，在达到边界时，斜向拖动会变现为无法拖动或者卡顿

Cropper version

2.0.0-rc.2

Steps to reproduce

官方示例，两个限制边缘都不行，卡顿，或者卡住

What is expected?

预期跟v1相同，在达到边界时只是不能出去，但是其他方向还是可以流畅的拖动

What is actually happening?

卡住

selection可以使用这个方法，prevent后，手动设置边界为最大/最小值：
如果启用了cropper-shade，mask有拖影的问题还没解决（悲

if (!this.inSelection(selection, maxSelection)) {
event.preventDefault();

// 计算约束后的位置
let constrainedX = selection.x;
let constrainedY = selection.y;
let constrainedWidth = selection.width;
let constrainedHeight = selection.height;

// 约束X坐标
if (selection.x < maxSelection.x) {
constrainedX = maxSelection.x;
} else if (selection.x + selection.width > maxSelection.x + maxSelection.width) {
constrainedX = maxSelection.x + maxSelection.width - selection.width;
}

// 约束Y坐标
if (selection.y < maxSelection.y) {
constrainedY = maxSelection.y;
} else if (selection.y + selection.height > maxSelection.y + maxSelection.height) {
constrainedY = maxSelection.y + maxSelection.height - selection.height;
}

// 如果宽度超出，调整宽度
if (selection.width > maxSelection.width) {
constrainedWidth = maxSelection.width;
constrainedX = maxSelection.x;
}

// 如果高度超出，调整高度
if (selection.height > maxSelection.height) {
constrainedHeight = maxSelection.height;
constrainedY = maxSelection.y;
}

// 使用$change方法同时设置位置和大小
const cropperSelection = event.target;
cropperSelection.$moveTo(constrainedX, constrainedY);
}

已经改1.6.2版本了，2.0问题好多

这个问题应该在触发事件之前处理，而不是触发事件之后。所以单纯的从外部修改，效果不好。就会卡或者闪烁。

I was having issues with having boundaries/limits where if my selection was hitting the corner or multiple edges my selection would freeze and no longer allow me to resize. It turned out that I was also setting aspect-ratio which causes the selection to move while resizing (replicable in the cropper.js playground). After setting precise on the cropper-selection it no longer was moving while resizing and would no longer freeze my selection on resize. I am not sure if this is the same issue but this is what helped me.
