[Bug] Blizzard Area POI tooltip secret-value SetWidth error

[alexv4138]

Summary

Hovering a map POI can trigger a secret-value error in Blizzard's tooltip widget code while World Quest Tab 12.0.11 is installed.

This is not the normal WQT quest tooltip path: the stack enters through Blizzard_SharedMapDataProviders/QuestOfferDataProvider.lua and AreaPoiUtil.lua. WQT's saved profile has no override for general.useCustomTooltip, so the current default true should apply.

I am reporting this here in case one of WQT's map hooks leaves this Blizzard Area POI tooltip path tainted. It may also be a Blizzard-only bug.

Error

Message: .../Mainline/Blizzard_UIWidgetTemplateTextWithState.lua:31: bad argument #1 to 'SetWidth' (Usage: self:SetWidth(width). Secret values are only allowed during untainted execution for this argument.)

Relevant locals:

widgetType=8

widgetSetID=1333
text=" Council of Dornogal"

Environment

• World Quest Tab: 12.0.11
• WoW Retail interface: 120005
• BWQDB.global.profiles[0].general is empty, so useCustomTooltip = true should come from defaults.
• No taint.log was present locally.

Notes

I have not reproduced this with World Quest Tab disabled or with all addons disabled yet, so addon ownership is not confirmed.
