The "Save" button seems to work, but the image is no longer displayed in "Edit" mode and the it's wrongly saved. I have logged this issue in #3848.
I will verify again this issue after #3848 will be fixed, to make sure that the "Save" functionality works as expected.

I have retested this issue on latest Screenshots 28.0.0 dev version and is no longer reproducible. The "Save" button works and the image is displayed.
