Pulldowns stopped working

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

Summary
Workflow template pulldown menus in Templates do not work on Windows in my ComfyUI venv install.

Environment
- OS: Windows
- Install type: manual ComfyUI install in virtual environment
- comfyui_frontend_package: 1.42.10
- comfyui_workflow_templates: 0.9.47
- comfyui-embedded-docs: 0.4.3

What happens
- Pulldown menus in Templates do not work.
- Clicking them does nothing / they do not function correctly.

What I expected
- The pulldown menus should open and allow selection normally.

What I tried
- Reinstalled comfyui-workflow-templates 0.9.47
- Downgraded comfyui-workflow-templates to 0.9.46
- Cleared browser cache / site data
- Tried different browsers
- No change

What fixed it
Downgrading only the frontend package fixed the issue:

python -m pip install --no-cache-dir --force-reinstall comfyui-frontend-package==1.41.21

After that, the pulldown menus worked again.

Notes
This makes it look like a frontend regression or a frontend/templates compatibility issue, rather than a problem in comfyui-workflow-templates itself.

### Steps to Reproduce

1. Browse Templates in comfyui
2. Press a pulldown menu (like model filter)
