[Bug]: Add combo and render will cause strange behavior #6804

It seems like you're experiencing an issue with the antv-dagre layout in G6 when adding a combo and rendering immediately. This can sometimes lead to unexpected behavior due to the sequence of operations.

Here are a few suggestions you might try to resolve or work around the issue:

1. Delay Rendering: After adding the combo with setData, try introducing a slight delay before calling graph.render(). This can sometimes help in ensuring that all data changes are fully processed before rendering.

2. Check Data Integrity: Ensure that the data being passed to setData is correctly structured and complete. Incomplete or incorrect data can sometimes lead to rendering issues.

3. Use graph.updateLayout(): Instead of calling graph.render() immediately, you might want to try using graph.updateLayout() to see if it resolves the issue.

4. Debugging: Use console logs or debugging tools to inspect the state of the graph and data before and after calling setData and render. This might give you insights into what's going wrong.

If these suggestions do not resolve the issue, it might be beneficial to look into the specific implementation details or consider reaching out to the G6 community for more targeted assistance.

If you have any further questions or need more detailed help, feel free to ask!

BTW, when I use graph render in my local, graph render would not resolve in this scenario

ah, once antv-dagre meets empty combo, it would cause the issue

and it may related, that the render would cause the page to freeze.
