描述

Downshift (useComboBox) is set up for Home and End keys to select the first or last option in the dropdown. However, the WAI-ARIA ListBox spec suggests that those keys should have their normal behavior of moving the cursor to the beginning/end of the text input.

研究方向: Investigate the useCombobox hook in downshift, particularly the keydown event handler for Home and End keys. The current behavior selects the first/last item, but the WAI ARIA spec expects cursor movement in the input. Look at the code in src/hooks/useCombobox/ and identify where key events are dispatched. The fix likely involves changing the default behavior of those keys to not call selectItem but rather move cursor. Ensure existing tests are updated accordingly.
