Blizzard_UIWidgetTemplateTextWithState tainting issue

Mainline/Blizzard_UIWidgetTemplateTextWithState.lua:35: attempt to perform arithmetic on local 'textHeight' (a secret number value tainted by 'Decursive'),

This is probably caused by Decursive's usage of GameTooltip... I only use AddLines on that but I'm not sure if I'm doing something wrong or if it's Blizzard's fault...

I would need a [taintlog ](https://wowpedia.fandom.com/wiki/CVar_taintLog) but the issue seems very random.

The error trace points to Blizzard_UIWidgetTemplateTextWithState.lua line 35, where a 'secret number value tainted by Decursive' causes an arithmetic error. Examine Decursive's interaction with GameTooltip, particularly any AddLines calls. Enable taintLog via CVar to capture the taint chain. Review the Decursive code that modifies GameTooltip to identify the source of taint.
