The change of quavers to semiquavers introduced by EE is right, as far as the rules of rhythmic notation are concerned. However, according to Chopin, the seemingly wrong original notation was most probably aimed at a calm, slightly slower performance of this figure. The same applies to b. 23.
See also b. 79 as well as the Prelude No. 18 in F Minor, b. 12, the Concerto in F Minor, Op. 21, 1st mov., b. 93 or the Nocturnes, Op. 9: No. 1 in B
Minor, b. 73 and No. 2 in E Major, b. 16.
