Research direction
Start by reproducing the bug on an iPhone Safari browser. Examine the cropperjs source code, particularly the event handlers for touch interactions (e.g., in src/js/cropper.js or similar). Investigate if the issue is caused by conflicting pointer event handling or improper event prevention during page navigation. Look for Safari specific workarounds in existing code or issues.
