Map Data Provider Memory Usage PSA
 

If you have an addon that uses the new map data provider mixins and it looks like it has high memory usage when you mouse over the world map don't worry it isn't your fault. The memory usage is coming from AreaLabelFrameMixin:OnUpdate() but since the addon uses same system as Blizzards mixin it is getting the blame. If you have more than one addon that is using the system it will just blame the first addon that was loaded.
