Worked on the tukui-org/ElvUI repository to address stability and compatibility issues related to tooltip handling for LDB plugins. Focused on Lua scripting and UI development, the work involved implementing a targeted fix to ensure the correct tooltip owner context is set when displaying custom tooltips. This adjustment resolved problems where tooltips would not display or function as intended, improving reliability for plugin users. The approach required careful debugging and precise change management within the Lua codebase, ultimately reducing user-reported issues and maintenance overhead. The contribution enhanced the core UI behavior without introducing new features, emphasizing quality and maintainability.
