1. Create a Layout, add a panel, load an image, click OK.
2. Delete (close) the image by closing it in the branch -> the Layout transformation thumbnail gets also removed.
3. Repeat the step 1.
4. Remove (close) the whole branch containing the image loaded into the panel ->
A. If the image was the only one in the branch, you get the result as in 2.
B. If there were at least two images in the branch, the Layout transformatin is preserved, only the panel gets empty. Though it may be an unintended by the design, in my opinion this is a preferred behaviour.
An additional observation.
The Layout transformation thumbnail in step 2. gets removed even if you already have one more panels in the layout page. This consequently makes you lose the whole work.
Deleting images loaded into Layput panels.
