Repro steps
- 1.Navigate to Ant Design DatePicker documentation under the 'Choose Time' section.
- 2.Click on the RangePicker input with showTime to open the calendar dropdown.
- 3.Select a start date (e.g., September 10, 2026).
- 4.Hover over another date (e.g., September 17, 2026 or September 5, 2026) to select an end date.
Expected
The selected start date should remain highlighted, and a range hover preview/highlight should connect the start date to the hovered end date.
Actual
The start date (September 10) loses its active highlight completely as soon as another date cell is hovered.
Evidence
visualAt 9.0s, September 10 is highlighted in blue as the active selected start date. At 13.0s, hovering over September 17 highlights September 17 but completely clears the highlight and range styling on September 10.
visualAt 17.0s, hovering over September 5 similarly shows only September 5 highlighted, with September 10 remaining unhighlighted.
Issue markdown (copy-paste ready)
### Summary When selecting a start date in Ant Design's `RangePicker` configured with `showTime`, hovering over another date to select an end date causes the previously selected start date's highlight to disappear entirely rather than maintaining the start date highlight and rendering a range selection preview. ### Steps to Reproduce 1. Go to the DatePicker documentation (`/components/date-picker`) under the **Choose Time** example. 2. Open the RangePicker dropdown popup. 3. Click a start date (e.g., September 10, 2026). 4. Hover the cursor over a subsequent date (e.g., September 17, 2026) or a preceding date (e.g., September 5, 2026). ### Expected Behavior The selected start date should remain highlighted, and hovering over target end dates should render a visual range preview between the start date and hovered date. ### Actual Behavior The start date's active highlight disappears upon hovering over other calendar cells, leaving only the hovered cell styled. *Recorded with SceneRecap.*
