Memory not released in Safari when editing multiple images

When multiple images are uploaded, page memory is adding up and never released. Especially when using mobile devices, this results in the WebView to eventually reload (this is especially problematic when Cropper.js is implemented in a page with other information, as that information would then be lost).

To Reproduce: While monitoring memory usage in Safari's Web Inspector 1 - Upload image 2 - Upload another image ..n - Upload another image

Screenshots

Tested on:

• macOS 12 Monterey / iOS 15
• Safari 15.5
• Cropper.js Version v1.5.12 ( issue can be reproduced on https://fengyuanchen.github.io/cropperjs/ )
