During February 2025, Dittgen focused on improving user experience in the maplibre/maplibre-gl-js repository by addressing a nuanced issue with hover popups on overlapping map features. Using JavaScript and front end development skills, Dittgen replaced the mouseenter event listener with mousemove and implemented logic to track the current feature’s coordinates. This ensured that the popup updated only when the cursor moved to a different feature, reducing unnecessary updates and visual flicker. The targeted bug fix enhanced interaction reliability for feature-dense maps, demonstrating careful attention to event handling and user interface behavior in a complex, real-world mapping application.
