<!-- Greeting --> Hi @DTaa2105ta! I'm [Dosu](https://go.dosu.dev/dosubot) and Iām helping the superset team. <!-- Answer --> This is a **known bug** that has been reported in [issue #37569](https://github.com/apache/superset/issues/37569) and [#37761](https://github.com/apache/superset/issues/37761#issuecomment-3862200442). **Browser-specific behavior:** - Chrome 145+ and Edge 145+: Hover highlights remain stuck (affected) - Firefox 148: Works correctly **Root cause:** There's a conflict between hand-written `mouseover`/`mouseout` handlers and Datamap's built-in `highlightOnHover` behavior in [WorldMap.js](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/legacy-plugin-chart-world-map/src/WorldMap.js). The execution order varies across browser versions, and in Chrome/Edge 145+, the custom `mouseout` handler actually prevents the highlight from resetting. **Proposed fix:** Remove the hand-written `mouseover`/`mouseout` handlers and rely entirely on Datamap's built-in `highlightOnHover` behavior, which resolves the issue across all browsers. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
