TYPO3 Core

I can reproduce this error with typo3 8.7.9 and firefox 58.0.1. With Chrome 63, Microsoft Edge 41 and Internet Explorer 11 it works as usual.

Same here.

I added

null !== this.currentCropVariant ||

as a workaround to typo3/sysext/backend/Resources/Public/JavaScript/ImageManipulation.js:

// If we start without an cropArea, maximize the cropper
if (null == this.currentCropVariant || ImageManipulation.isEmptyArea(this.currentCropVariant.cropArea)) {
    this.defaultOpts = $.extend({
        autoCropArea: 1,
    }, this.defaultOpts);
}

We can reproduce this issue too: Chrome 64.0.3282.186 & Firefox 58.0.2 + Typo3 8.7.10.

I can confirm that the workaround mentioned in note 2 works for Firefox 58 and Typo3 8.7.11.

However, there is a typo in note 2. The first box should be

"null == this.currentCropVariant ||"

(same as the second box)

I just tried with Typo3 versions 9.5.15 and 8.7.32 under Firefox 75. I was not able to reproduce the issue under these versions.
