在键入现有内容并开始向后键入后，React DraftJS光标会自动跳到开始处吗？

npm install draft-js@latest react-draft-wysiwyg@latest

import React, { useRef } from 'react';
import { EditorState, ContentState } from 'draft-js';
import { Editor } from 'react-draft-wysiwyg';
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css';

const MyEditor = () => {
  const editorRef = useRef(null);
  const [editorState, setEditorState] = React.useState(EditorState.createWithContent(ContentState.createFromText('')));

  const handleKeyCommand = (command, editorState) => {
    const newState = RichUtils.handleKeyCommand(editorState, command);
    if (newState) {
      setEditorState(newState);
      return 'handled';
    }
    return 'not-handled';
  };

  return (
    <Editor
      ref={editorRef}
      editorState={editorState}
      onEditorStateChange={setEditorState}
      handleKeyCommand={handleKeyCommand}
    />
  );
};

export default MyEditor;

const handleKeyCommand = (command, editorState) => {
  console.log('Current command:', command);
  console.log('Current editor state:', editorState);
  const newState = RichUtils.handleKeyCommand(editorState, command);
  if (newState) {
    setEditorState(newState);
    return 'handled';
  }
  return 'not-handled';
};
