The arpeggio in GC was added most probably by Chopin (cf. the arpeggios written with the hand of a copyist in the Etude in A minor, No. 11, bar 53-54). Therefore, lack of the sign in FE is probably a result of the composer's inattention. The sustention of the chord marked in FES, compatible with Chopin's tendency to eliminate the strokes of the accompanying part together with the sounds of the top voice (cf. the note to bar 30), may be considered as an equal variant.
