💡 Background and Solution

Background
Chinese

• 在官方文档展开与粘性表头中，出现鼠标移入存在同级展开的元素行后 hover 会扩散到其他非当前视觉焦点链条上，导致 hover 得不到预期效果，仅在 expand-sticky 中发现该行为，其余示例 hover 表现符合预期。目前 Ant Design 库的 Headless Table 存在同样的问题，请酌情考虑合并，我会同步 PR 给 Ant Design 的 Headless Table PR

English

• In the official documentation Expandable and Sticky Headers, the hover effect spreads to other elements outside the current visual focus chain when the mouse hovers over a row containing an element with a sibling expand component. This causes the hover effect to behave unexpectedly. This behavior has only been observed in the expand-sticky example; in all other examples, the hover effect behaves as expected. The Headless Table in the current Ant Design library has the same issue. Please consider merging this as appropriate; I will submit a PR to the Ant Design Headless Table PR.
