The icon to change to the new image.
The icon doesn't update.
I can confirm this bug on Files 3.26.0 on Ubuntu 17.10, I can also confirm it on the Files Nightly (3.28.0) Flatpak. A
nautilus --quit and relaunch of Files updates the thumbnail as expected.
This bug can be reproduced even if you delete the folder, create a new one (with the same name and in the same directory), and try and give it a thumbnail of the new image (with the same name and inside the folder). The old image's thumbnail is used until a
nautilus --quit and starting up Files again.
