The slur visible in A under the quaver triplet in bars 293 and 297 was most probably overlooked both in GE1 and in GE2 (it is understandable in bar 293, in which the slur blends into the 
sign). We do not convey these slurs in the main text, since they seem to be triplet slurs, which we generally do not include (General Editorial Principles, p. 16), and which could have been left in A by accident. However, it is not a typical situation, hence it cannot be excluded that Chopin indeed envisaged double slurs in this place.
