When trying to convert Japanese using IME in the editor, the character is entered before selecting

Hello. I am a Web Developer from Japan.
Thank you very much for making the module react-codemirror2.

When I try to convert Japanese using IME, characters are entered into the editor without permission after a few seconds.

import {UnControlled as Codemirror} from 'react-codemirror2';
import NoSSR from 'react-no-ssr';

handleChange(value) {
    if (this._subscription) {
      this._editorContent$.onNext(value);
    }
  }

  render() {
    const { executeChallenge, content, height, mode } = this.props;
    const style = {};
    return (
      <div
        className='challenges-editor'
        style={ style }
        >
        <NoSSR>
          <Codemirror
            value={ content }
            options={ this.createOptions({ executeChallenge, mode, options }) }
            autoCursor={false}
            onChange={(editor, data, value)=> {
              this.handleChange(value);
            }}
          />
        </NoSSR>
      </div>
    );
  }

The following URL is the problem we are facing.

Also, this bug does not occur at the end of the editor.

Is there any solution?

こんにちは。私は日本のエンジニアです。モジュールを作ってくれて本当にありがとうございます。

IMEを使用して日本語を変換しようとすると、数秒後に文字が勝手にエディターに入力されてしまいます。

また、エディターの末尾ではこのバグは起きません。

解決策はありますでしょうか？
