React DraftJS cursor auto jumps to beginning after typing in existing content and started typing backwards?

I'm using DraftJS to edit text contents, but when I tried to edit any existing contents that I've retrieved from DB and loaded into the Editor, the cursor auto jumps to the beginning of the texts and I started typing from backwards.

I've imported the Editor into Bulletin.js, so I have to get the content by passing getContent into Editor and retrieve back the raw html by using getContent in the handleEditorChange function of the Editor.

I've found out that if I've removed the getContent function to pass back the raw HTML in handleEditorChange, the editor works normally, but then I won't be able to get the html content back to Bulletin.js.

Here's the codesandbox that I've created for reference.

The issue is that you set on every change a new EditorState here:

useEffect(() => {
  if (htmlContent) {
    let convertedToHTML = decodeURIComponent(htmlContent);
    const blocksFromHtml = htmlToDraft(convertedToHTML);
    const { contentBlocks, entityMap } = blocksFromHtml;
    const contentState = ContentState.createFromBlockArray(
      contentBlocks,
      entityMap
    );
    setEditorState(EditorState.createWithContent(contentState));
  }
}, [htmlContent]);

htmlContent is always changing as you convert the EditorState to HTML on every change via the getContent function.

If you want to initialize your EditorState with the htmlContent you can do it in the useState function and remove the useEffect:

const [editorState, setEditorState] = useState(() => {
  if (htmlContent) {
    let convertedToHTML = decodeURIComponent(htmlContent);
    const blocksFromHtml = htmlToDraft(convertedToHTML);
    const { contentBlocks, entityMap } = blocksFromHtml;
    const contentState = ContentState.createFromBlockArray(
      contentBlocks,
      entityMap
    );
    return EditorState.createWithContent(contentState);
  }
  return EditorState.createEmpty()
});
