When filterable={true} is set, the filter input field does not respond to Home and End keys. The keys are swallowed and never reach the input element, making cursor navigation less convenient.

Steps to Reproduce:
- Render a DropDownList with filterable={true}
- Open the dropdown and type a string into the filter input
- Press Home, End, Shift+Home, or Shift+End

Expected: cursor moves to start/end of input; Shift+Home/Shift+End selects text
Actual: nothing happens in the input field
