Dear Maintainer,

* What led up to the situation?

Several images in a folder, and I want to rotate some of them by 90°

(I'm using MATE in German, so my translations of the actions might not be 100%
what is shown there in English.)

* What exactly did you do (or not do) that was effective (or
ineffective)?

Opening the first image, clicking on Rotate 90° left/right; moving on to the
next one etc; then closing the window, eom asks: "Do you want to save changes"
(with the possibility to tick/untick every changed image) — yes (for all).

* What was the outcome of this action?

It looks like all changed images are saved, as they are reloading thumbnails.
But only the last image is actually rotated, all others keep as they were. This
was working in debian buster (so probably eom 1.20.2)

* What outcome did you expect instead?

It should save all changed images, not only the last one.
