The slur over the chords is in Ap, Chopin wrote it also in FEcor, however in finished FE (→EE) the sign was omitted, probably due to an overlap of a few Chopin's entries in this place. It is unclear how the slur appeared in GE; probably it is an accurate revision of the editor, e.g., on the basis of comparison with bar 44 (see also the remark in the next bar). In EE3 (→EE4) the slur was added under the chords, which is certainly an arbitrary revision.
