According to the editors, the lack of a tie to g3 in #ApI may just be Chopin's oversight (the missing before this crotchet is definitely an error).

In the sources there are no naturals specifying the sound of the top note of the mordents. However, the phrase is clearly kept in the key of F major, which is indicated by the arrangement of the individual chords within the four-bar section. The fact that it is also here that Chopin heard the key of F major and not of B major is proven by the e2 notes present in the figuration in b. 112-113 (116-117), particularly in the melody by the end of b. 188. Omission of accidentals specifying the sound of secondary mordent, trill or grupetto notes was rather a rule than an exception in the Chopinesque notation.

In AsI the accidentals restoring c1 and b at the end of b. 137 are missing; the  raising e1 to e1 in b. 138 is absent too. A similar situation occurs in the L.H. part, which is marked in an abridged manner as doubling in unison the R.H. part. In A and the editions the notation is correct.
