Spells: Charisma buff overwriting brilliance?

[guyzmo52]

The last patch note mentions that Brilliance/Insight should now stack with charisma buffs but actually it still does not work:

Content
Nilbog: Karg Icebear's quests are multiquestable.
Nilbog: Greenblood zombies, Vilnius the small will not spawn until appropriate era.
Nilbog: Byzar Bloodforge's quests are multiquestable. 'Trumpy Irontoe' quest requires amiable or better faction.
Nilbog: Added a lot of missing dialogue to Kaladim npcs.
Telin: Corrected Cordelia Minster's level range and loot.
Telin: Many more quest items and mobs will no longer drop or spawn until the appropriate era.
Telin: Prior to Kunark, the Robe of the Lost Circle will have its original classic stats.
Telin: Pre-Kunark Insight and Brilliance should now stack with charisma buffs.
