Issue demo:
https://codesandbox.io/s/ji-ben-antd-4-18-5-forked-orrdd?file=/index.js

Have tried to add test case, but not success to simulate keyDown event（official issue）:

it('input and textarea cursor can be moved by arrow',()=>{constwrapper=mount(<inputvalue='123'onFocus={e=>e.target}/>,);constinput=wrapper.find('input');input.simulate('focus');constinputNode=input.getDOMNode();expect(inputNode.selectionStart).toEqual(0);input.simulate('keyDown',{which: KeyCode.A,keyCode: KeyCode.A});expect(inputNode.value).toEqual('123A');expect(inputNode.selectionStart).toEqual(1);input.simulate('keyDown',{which: KeyCode.LEFT});expect(inputNode.selectionStart).toEqual(0);consttextarea=wrapper.find('textarea');textarea.simulate('click');expect(textarea.selectionStart).toEqual(0);wrapper.find('Overflow').simulate('keyDown',{which: KeyCode.RIGHT});expect(textarea.selectionStart).toEqual(1);wrapper.find('Overflow').simulate('keyDown',{which: KeyCode.LEFT});expect(textarea.selectionStart).toEqual(0);});
