A lacking  before the penultimate quaver is most probably a mistake by Chopin. The accidental was added by the revisers in both GE and EE.

Same as in bar 4, FE, EE1 and GE1 misinterpreted here the abbreviated notation of FC and of the remaining Stichvorlage manuscripts, giving the 2nd, 3rd and 4th group of semiquavers without any accidentals. The mistake was corrected in EE2 (→EE3) and GE2 (→GE3).

In Atut (→FE), there is no  restoring d1. Chopin's patent mistake was corrected in GE and EE.

The missing  restoring d1 is almost certainly an oversight of Chopin in A (→FC,FE), which is proven by the naturals in AB, ACh and the one added in b. 8 in FES. The accidentals were also added by the revisers of GE and EE.

According to us, the missing accidental before the penultimate note in the roulade is almost certainly Chopin's error, one of his most frequent mistakes. It is supported by similar melodic phrases in other places in the Prelude, e.g. in b. 4-5 (b at the beginning of b. 5) or an octave higher in the discussed bar (the 10th semiquaver, e). Cf. the note in the Prelude in C minor, Op. 28 No. 20, b. 3.
