Describe the bug

This issue occurs when using classic Jupyter Notebook command mode keyboard shortcuts to duplicate an executed cell with iTables widget output. The iTable in the copied cell appears to get stuck indefinitely attempting to loading external resources.

This appears to be platform specific - on JupyterLab, copying cells with iTables output works correctly.

• OS: Mac OS Sonoma
• Browser: Google Chrome
• Graph Notebook Version: 4.4.0
• Graph Database & Version: Amazon Neptune 1.3.2.0

To Reproduce

1. Create a new classic Jupyter Notebook instance.
2. Execute any graph query in %%oc/%%gremlin/%%sparql
3. Click to the left of the executed cell to enter command mode.
4. Press c, then press v.
5. Observe the iTables widget error in the copied cell's output.
