The tie visible in GC before the chord means an arpeggio in this context. The version of GE, repeated then in EE2, is a result of a routine revision – the sign was moved to the side of the note head of the d1 grace note, which gave it a form of a tie sustaining the grace note (cf. the note on the part of the L.H.). No slur in FE (→EE1) is most probably an oversight.
FE1 includes an erroneous c1 as the grace note, which was corrected in the next impressions.
