An arpeggio preceded by a grace note, resulting in a repetition of the bottom chord note, belongs to Chopin's favourite ornaments – cf. e.g. bars 18 and 320 or the Polonaise in F
minor, Op. 44, bar 27 and analog. Therefore, it seems unlikely that the small slur added in FE2, reducing the ornament to a common arpeggio, could have been coming from Chopin. The absence of the small slur in EE suggests that the mark was added in the last stage of proofreading FE2.
