The staccato mark in A, despite its smallness, is clearly prolonged (vertically). Both Fontana in FC and the engraver of FE regarded it as a wedge. GE1 and EE changed it to a dot, which can be considered acceptable, taking into account the fact that both passage E major sections feature only dots except for this place, including in analogous b. 438 & 446. GE2 (→GE3) did not include the mark, which could easily be considered an oversight if it were not for the dot in analogous b. 446, which was also left out.
