react-quill How to do undo & redo on button click?

问题

I've tried by acquiring the quill object like this:

• got the ref from ReactQuill Component <ReactQuill ref={this.setRef}/>

• and then in componentDidMount got the quill object itself this.quillRef= this.reactQuillRef.getEditor();

• and then I call this.quillRef.history.undo() / this.quillRef.history.redo()

But there seems to be a problem with focus, kinda like ReactQuill and Quill are out of sync. When i do undo or redo sometimes it just moves the cursor.

But everything works fine on ctrl + z and ctrl + y.
