If the parent view is scrollable and the crop frame is moved about the touch event will be handled by the scrollable element rather than actually translating the crop frame
This causes a lag in the translation of the crop frame until it reaches the bounds of the scrollable element
Recommendation
Use the no-scroll npm package to disable scrolling entirely on the document while the image editing modal is open and then re-enable it when it is closed
