In A the f note at the beginning of bar 296 seems to be a semibreve, since it does not have a stem. The same applies to the f1 note in bar 308. In both cases we are dealing with inaccuracies, which is proven by the ties to these notes (they are supposed to be held to the 2nd half of the bar). Therefore, in both bars we consider the version with a minim to be the A text; it was already introduced by GE (→FE,EE,IE).
