Not A Bug Akal Pakal does not trigger on Opponent end step as expected

[zorkmead]

With Akal Pakal, First Among Equals on battlefield, on opponents turn, cast Brackish Blunder targeting my own tapped Pathfinder Axejaw returning to hand and creating a Map token. Akal Pakal did not trigger at eot.

Did you cast the spell before your end step? If you cast it during your end step, Akal Pakal won't trigger. The latest moment you need to cast it is your opponent's postcombat main phase.

Replay confirms this was the case - end step cast = no trigger
