bug

Fixed in PTR 2.0.3.23025; present in v2.0.3.22904, v2.0.3: per-ability instance fields sometimes wrongly apply to all ability instances of the base type. See BlzSetAbilityStringLevelField for test code.

Bug report: https://us.forums.blizzard.com/en/warcraft3/t/ability-specific-tooltip-natives-broken-in-v20322978/36601

Test code (Lua):

heroA = CreateUnit(Player(0), FourCC("Otch"), -100, 0, 90)
heroB = CreateUnit(Player(0), FourCC("Otch"), 100, 0, 90)

abilCode = FourCC"AOmi"

print(UnitAddAbility(heroA, abilCode))
print(UnitAddAbility(heroB, abilCode))

abilityA = BlzGetUnitAbility(heroA, abilCode)
abilityB = BlzGetUnitAbility(heroB, abilCode)

print("ability pointers:", tostring(abilityA), tostring(abilityB))

BlzSetAbilityStringLevelField(abilityB, ABILITY_SLF_TOOLTIP_NORMAL, 0, "this is ability B tooltip")
BlzSetAbilityStringLevelField(abilityB, ABILITY_SLF_TOOLTIP_NORMAL_EXTENDED, 0, "this is ability B tooltip extended")

heroC = CreateUnit(Player(0), FourCC("Otch"), 200, 0, 90)
print(UnitAddAbility(heroC, abilCode))
abilityC = BlzGetUnitAbility(heroC, abilCode)

-- String Level Field, wrongly applies to all in 2.0.3
print("Expected: default / changed / default")
print(BlzGetAbilityStringLevelField(abilityA, ABILITY_SLF_TOOLTIP_NORMAL, 0))
print(BlzGetAbilityStringLevelField(abilityB, ABILITY_SLF_TOOLTIP_NORMAL, 0))
print(BlzGetAbilityStringLevelField(abilityC, ABILITY_SLF_TOOLTIP_NORMAL, 0))

-- Integer Level Field test, works in 2.0.3
print("expected: changed (77), unchanged (125)")
print(BlzGetAbilityIntegerLevelField(abilityA, ABILITY_ILF_MANA_COST, 0))
print(BlzSetAbilityIntegerLevelField(abilityA, ABILITY_ILF_MANA_COST, 0, 77))
print(BlzGetAbilityIntegerLevelField(abilityA, ABILITY_ILF_MANA_COST, 0))
print(BlzGetAbilityIntegerLevelField(abilityB, ABILITY_ILF_MANA_COST, 0))

-- Integer Field test, wrongly applies to all in 2.0.3
-- v2.0.2: sets value, but has no effect
print(BlzGetAbilityIntegerField(abilityA, ABILITY_IF_BUTTON_POSITION_NORMAL_X))
print(BlzSetAbilityIntegerField(abilityA, ABILITY_IF_BUTTON_POSITION_NORMAL_X, 2))
