Despite the fact that the a2-a3 octave is possible as far as the sound is concerned (cf. the Prelude in F minor, Op. 28 No. 8, bars 6 and 20), Chopin's mistake seems to be almost certain here, even due to the pianistic issues. The conclusion is confirmed by Chopin's proofreading performed in this place in FE (→GE,EE).

In A (→FE) there is no  raising d2 to d2 on the 5th quaver and the  lowering g1 to g1 on the 11th quaver. These patent errors were corrected in GE and EE.

f4 in A & GE

f3 in FE (→EE)
..

The longer octave sign in A is almost certainly Chopin's mistake. The error reached GE, where it remained unnoticed, through a proof copy of FE. In the last proofreading of FE (→EE), f4 was changed to f3, probably on the composer's request.
