The Prop option spellcheck is not working

Even with spellcheck={true}, nothing happens when there is typo

<AceEditor
        ref='editor'
        mode="markdown"
        theme="github"
        height="100%"
        width="100%"
        value={value}
        onChange={onSumChange}
        wrapEnabled={true}
        spellcheck={true}
        showGutter={false}
        focus={true}
