The ending of the slur of A reaching f3 was most probably added later, replacing the previous markings, analogous to the two preceding figures (staccato dot and slur to the last semiquaver in bar 297). It is unclear why this distinct notation was not reproduced by GE (→FE,EE). Perhaps it was influenced by the layout, in which bar 298 opens a new line. Chopin's intervention seems highly unlikely here.
The absence of the wedge in EE is most probably an oversight.
The unclear entry in AsI may be a superimposition of two versions – an earlier one with two wedges (which, apart from a different kind of staccato mark, corresponds to the original A version) and a later one in which e3-f3 are slurred which corresponds to the ultimate A version.
