FE overlooked the  restoring e1 on the 5th R.H. quaver. The accidental was added in EE; it was also entered into FEJ, probably by Chopin.

f1 in A (→FC,FEEE) & GE2 (→GE3)

c1-f1 in GE1

The version of GE1 must be a mistake – the engraver most probably saw a note where the stem and the ledger line meet in FC, the point of contact of which resulted in a small protrusion (such situations are also to be found in Chopin's autographs, where it can be difficult to settle them, cf., e.g. the Etude in A Major, Op. 10 No. 10, b. 76).

In A one can see that Chopin initially wrote e as the 1st quaver; it was only afterwards that he crossed it out and replaced it with E. See also the Prelude in A Major, b. 13 and 15.

The crossing-out in the L.H. part visible in A allows us to decipher the initial version of the 2nd crotchet of the bar as an arpeggiated F-a tenth. According to us, the pedalling markings added in the 2nd half of the bar were related to the wide L.H. span of that version. After changing the tenth to a third, Chopin left the pedalling markings (not necessary in terms of harmony); he could have assumed that pedal would enrich the sound of this final dominant chord (provided with an accent!) regardless of the span of the chord, be it small or big.
