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.
