As Delhi Sultanate, when healing a unit that has the Zeal buff (“Units healed by Scholars gain 50% attack speed for 3 seconds”), as soon as it has been healed to full HP, rather than the buff persisting for the full 3 seconds, it disappears from the unit as soon as it hits full HP.
This doesn’t sound like it should be the case based on the description.
