On the available photograph of A, it is difficult to evaluate whether the dot visible over the 1st quaver is a staccato mark, an insignificant fleck of ink or the upper end of this note's stem. Therefore, in the main text we confide in the engraver of FE, who did not include this possible mark in the text. In similar contexts, Chopin would use both a version with a dot and a version without it, cf., e.g. b. 68 and 191 of the Ballade.
