https://it.wikipedia.org/w/index.php?title=Casco&diff=next&oldid=64464748 removes "righ" (in VE, the editor wouldn't be able to see that's misspelled, so s/he wouldn't try to change/remove it).
This is a visual editor selser bug -- VE should have protected this image and not given it to parsoid to convert. (Parsoid *may* preserve invalid format options in the future, see bug 62500.) Related: https://it.wikipedia.org/w/index.php?title=Terza_guerra_di_indipendenza_italiana&curid=232854&diff=64604490&oldid=64391386 displays the same issue ('float' is an invalid option). The first image is not properly being protected by selser, although the second one in the diff is.
(about my comment: the editor= the person who edits.)
This was caused by the same issue that dirtied about 400 edits on the French Wikipedia, and was fixed by the same fix. *** This bug has been marked as a duplicate of bug 62366 ***
