See https://it.wikipedia.org/w/index.php?title=Vallo_Atlantico&oldid=66317144&veaction=edit :
Reach the paragraph "Comandi del Vallo Atlantico", see there's a list there.
It looks weird because the syntax for the picture on the right is in the middle of the list.
Average user doesn't actually know/realize this and just wants to fix the list.
S/he will place the cursor right after the word "Danimarca" on the second line and hit Canc. The pic suddenly disappears.

(Right now there's a further bug 68708 which did lead to the image being removed without the user really noticing it: he noticed that the "Commando tedesco" line was not aligned properly and tried to fix that by going on that line and hitting Backspace. He didn't notice the pic getting highlighted and hit Backspace again, so the page lost focus and all he could see when he read the list again was that he had fixed it.)
