Due to asymmetrical alignment of the A slur with respect to the staccato dots, one could assume that it encompasses the entire 2nd half of the bar. However, according to us, Chopin almost certainly envisioned here a slur over the three quavers, as it was interpreted by GE (→EE,IE). The longer FE slur does not have to suggest that the FE editors had access to A, since engravers would often adjust slurs or dynamic hairpins to natural rhythmic groups, for example, groups of notes under one beam.
