 at the beginning of b. 87 is the only pedal marking in these bars in A. It is almost certainly an oversight by Chopin, who resumed writing markings after transitioning to a new line. FE (→GE,EE) added markings in b. 88, most probably at Chopin's request, while GE and EE also added a  at the end of b. 87.

The missing pedal markings at the end of b. 217 and in b. 218 in A must be Chopin's inadvertence, since it is the end of a line in A, which is conducive to oversights – after a moment of distraction, the composer resumed writing indications from a new line.
