How to Reset Change Event In Angular

Consider the following StackBlitz. If I select an image from my filesystem the image loads without problems. But if I now reload the same image from my filesystem a new event is not raised and the image is not loaded. My question is. What should I do to load the previously uploaded image again? In other words … how to reset the component’s cache so that a new event is emitted and in this way the same image can be loaded twice?

Finally, I would like to know why (change) works this way?
