 Hi @obermeister8080,

 I tried to reproduce the issue and got the following observation.

 For some images the crop handles worked just fine but for some others, the
 handle did not respond at all.

 I tested in both both Firefox [57.0.4 (64-bit)] and Chrome [Version
 63.0.3239.132 (Official Build) (64-bit)] on Ubuntu Linux and the behaviour
 was similar.

 What I have seen is if the image dimension is less than 512 x 512 sq. px.
 (which is the minimum required dimension as per on-screen message), the
 handles do not response.

 However, when I tried an image with dimension `width:height ::
 712px:417px`, the crop handle does not work. The reason is because the
 height is `417px`, which is already less than `512px`.

 But, the interesting thing is this image does not satisfy the on-screen
 instruction i.e.
 '''"''Site Icons should be square and AT LEAST 512×512 PIXELS.''".'''

 Since the crop handles only allow square cropping and we cannot drag side
 handles (only corner handles are accessible), images which cannot satisfy
 `512x512 sq. px.` size after cropping, the handles will probably not work.

 However, looking at the scenario, I should not be able to use `712px x
 417px` image or the on-screen instruction needs to be modified!
