b. 39-40
In the main text we include the staccato marks on the 4th beat of the bar, added in GE (→FE,EE,FESB). It is noteworthy that in A Chopin added the staccato indication after eight semiquavers, which suggests that he considered that the 4th beat of b. 39 (and most probably of b. 35 too), identical to the third one, would naturally "inherit" the articulation markings of the preceding one. Therefore, although the authenticity of the very marks is not entirely certain, the authenticity of the articulation they indicate absolutely is.
