Troll Warlord does not attack Legion Commander during Duel while under Battle Trance

[ryansamara10-lgtm]

When Troll Warlord uses Battle Trance and is attacking creeps, if Legion Commander initiates Duel, Troll Warlord this happens with axe aswell continues attacking nearby creeps instead of switching to Legion Commander.

Heroes Involved:

Troll Warlord
Legion Commander

Steps to Reproduce:

Pick Troll Warlord
Activate Battle Trance while attacking lane creeps
Have Legion Commander blink in and cast Duel on Troll
Observe Troll Warlord’s attack behavior

Expected Result:
Troll Warlord should be forced to attack Legion Commander for the full duration of Duel.

Actual Result:
Troll Warlord continues attacking creeps instead of Legion Commander during Duel.

Additional Notes:

Occurs when Troll is already mid-attack on another target before Duel starts
Seems related to Battle Trance forced targeting behavior
May be tied to target priority or attack order not updating on Duel cast

#4435 #16136 #14689 troll warlord not attacking at all if taunted during ult. still no fix since 2022?
expected to either change target to the one taunting, or keep the same target until his ult ends then change to taunted target.
