Neither in PE, which certainly recreates the layout of [A] accurately, nor in JC, the end of the Polonaise is explicitly marked. Double bar lines, the indication Trio in bar 52, and the generally known dance form allowed to understand the order and scope of particular sections without any difficulties.
Cf. the note concerning bar 103.
In EF, all performed sections are written out entirely, therefore, there is no need to insert the hints clarifying the piece's form.
