The staccato dots probably represent the initial version of articulation of these crotchets, which Chopin replaced with slurs. It is indicated by the A notation in bar 104, in which the dots over the 2nd and 3rd crotchet were overwritten with a slur (leaving the dot over the 4th crotchet must be considered an oversight in this situation). In the discussed bar all 3 dots present along with slurs remained unremoved, hence in the main text we provide them in a variant form (in brackets). Being convinced of our hypothesis, one can choose the version of the editions, devoid of these dots.
