Spinning icon not working with VS Code

[giswqs]

Description

I am trying to use the spinning icon for a button. It works preferctly in Jupyter Lab, but the button would not show up in VS Code.

Reproduce

button = widgets.Button(description='Running', icon='gear spin lg')
button

Expected behavior

Works in JupyterLab

Context

• ipywidgets version: 8.1.2
• Operating System and version: Linux
• Browser and version: VS Code 1.88.1

My guess is that the font-awesome version JupyterLab ships is not the same as the one used when using vscode.
