mobile - I cannot crop as I'd like to

[piotr-s-brainhub]

It is:

1. I open https://brainhubeu.github.io/react-file-input/docs/examples/cropTool
2. I add an image
3. I click save
4. I click on a point inside the image
5. It crops from the top-left edge to the clicked point.
6. I'm not able to change the selected area.

It should be:
6) I should be able to select any area for cropping as I can on the desktop.

As you can see, there are two problems:

1. I'm able to select only the bottom-right edge of the selection but the top-left is always the image edge.
2. I cannot change the selection.
