> ### Problem > Custom series elements with large datasets (~3000+ points) were being marked as `silent` / `ignore` by ECharts for performance reasons. As a result, **hover and emphasis (highlighting) did not work** even when `emphasis` was explicitly defined in `renderItem`. This is tracked in issue #21442. > > ### Solution > This PR ensures that any **custom element with an `emphasis` state** is not marked as silent or ignored. The fix is applied in `src/chart/custom/CustomView.ts` just before `toggleHoverEmphasis` is called. > > * Only elements with `emphasis` are affected > * `emphasisDisabled` is respected > * Large dataset performance remains unaffected > > ### How to Test > 1. Open the custom series example (CodeSandbox or `http://localhost:9001`) > 2. Set `dataCount` to ~3000-4000 > 3. Hover over the rectangles > 4. Observe that emphasis (highlight) works correctly > > ### Related Issue > Closes #21442 -- This is an automated message from the Apache Git Service.
