The pedalling of A (→GE→FE) is questionable in this bar. Initially, both this and the next bar had a whole-bar pedalling. Chopin then crossed out both signs in bar 436 and a 
in the discussed bar 435. It is difficult to guess what a sole 
mark left in this bar could mean in this context, hence it seems that Chopin committed a mistake: he either forgot to cross out the mark or he unnecessarily crossed out the mark. According to us, the latter option seems to be more plausible; therefore, in the main text we give a completed pedalling, written in brackets to signalise that its status is not entirely certain. EE added a in accordance with the harmonic sense.
