Python Server: context.identifier.toLowerCase is not a function

[yan12125]

• Netron app and version: 7.6.2 Python server
• OS and browser version: Arch Linux up-to-date + Firefox 125.0.2

Steps to Reproduce:

1. pip install 'netron==7.6.2'
2. netron model.onnx

In Firefox, I got a message box with an error:

TypeError context.identifier.toLowerCase is not a function

Please attach or link model files to reproduce the issue.

Any ONNX model fails. The issue also happens with the example model mentioned in README: https://github.com/onnx/models/raw/main/validated/vision/classification/squeezenet/model/squeezenet1.0-3.onnx

On the other hand, everything works fine if I use the "Open Model..." button to select a model file.
