Crop bug after Zoom method

[GangHyun95]

After reducing or increasing the size of the image through the zoom method, it works well until the crop area is created by dragging in startDrawingMode ('CROPPER').
However, if you try to resize the crop area by holding the edge or vertex of the crop area after creating the crop area, it will behave strangely.
And there are bugs, such as smaller images or out-of-scope cuts when using the crop(rect) method after designating the crop area after using the zoom method.
Is there any other way to solve this problem?
