The absence of a mordent both in EE and GE suggests that we are dealing with an oversight of the engraver of FE, which made its way to these editions; however, in FE it was corrected in the last stage of proofreading. In the main text we add an accidental – often omitted by Chopin in such situations – specifying the pitch of the mordent's top note.
