In the main text we keep the notation of A, which is a result of Chopin's reflection: the version featuring the dotted minim is the original one, crossed out in this and the previous analogous place (b. 274). The presence of that removed version both in FC and FE (→EE) may be puzzling, yet it is probably a result of the copyist's and the engraver's inattention. The missing dot in GE could be explained in the same way.
