User can drag image out of its container

[umutamac]

In my use case, users can drag the picture out of the designated area, which makes it harder to use for first-time users.

In the demos in the Readme, there is no such issue. For instance, I am not able to drag the picture anymore to the left after the right edge of the picture is at the right border of the container. This is also similar to how Photos work in Windows 10, and that is the desired behavior for me.

What could be the reason of this behavior?
