Wrong desktop picture set when setting desktop picture though correct one is shown elsewhere

[Wise Melon]

I have recently noticed that when going into gnome-photos that if one selects and image and then selects to set it as the desktop picture instead this image is set: WrongDesktopImage.png

But the strange thing is is that if I then go into the Activities Overview the correct desktop image is shown there: CorrectDesktopImageInActivitiesOverview.png

And if I go into the Background settings it shows the correct image as well, but I can never get the gnome-photos application to set the correct desktop image on the actual desktop though it sets it everywhere else: CorrectDesktopImageInSettings.png
