Still getting "Model not found" error instead of static figure when saving and re-opening the notebook

首先，使用 issue 中列出的版本在 JupyterLab 中复现保存并重新打开的工作流，然后检查报告中显示的 Chrome 控制台输出。当重新打开 notebook 时能够在没有“Model not found”错误的情况下渲染图形，即表示该 issue 已解决。

Hi, unfortunately, I am still seeing this error after re-opening the notebook.

The console log from Chrome:
