In ruWP use page "report an error in the article". VE panel has a menu "help" (?) -> Leave feedback. Anonymous user often confused and leave error message on the page "Leave feedback". Whether it is possible locally in ruWP add a new menu item "(?) -> report an error in the article" under the item "(?) -> Leave feedback about VE"?
Topic on VisualEditor/Feedback
You wouldn't need a new item, because Leave feedback is meant precisely to gather feedback about VE, not about random articles. You might try to create locally MediaWiki:Visualeditor-feedback-tool and adapt it. In my experience though that doesn't help much. Best,
