Chopin would use the dim. abbreviation much more frequently than dimin.; therefore, it is likely that the Viennese publisher changed it arbitrarily (the change does not affect the meaning of the indication). The composer could have entered it into [A] after Fontana had finished [FC]. Alternatively, it could have been overlooked in the basis for FE (→EE) or in the edition itself. Anyways, there are no reasons to doubt its authenticity, hence we give it in the main text.
