This came up while working on the new media dialog in VisualEditor. When there's a change in an image align attribute, the resulting wikitext adds the new alignment keyword instead of replacing the original.

Initial wikitext:
[[File:image.png|thumb|right|caption goes here|466x466px]]

After changing the image to right alignment (removing tright and replacing with tleft, and replacing the align attribute in the image object) -- the resulting wikitext post save is this:

[[File:image.png|thumb|right|caption goes here|466x466px|left]]
