[Bug]: Group Nodes : hidden in / outputs show + break on change

[PrometheusDante]

Frontend Version

ComfyUI_frontend v1.8.12
ComfyUI 0.3.13
ComfyUI-Manager V3.17.3

Expected Behavior

Inputs and outputs of group nodes should be hidden when toggled to be hidden, and not have any name changes.

Actual Behavior

All in- and outputs that were set to be hidden, but have auto-named unique descriptors, as it happens with nodes sharing widget names, are shown, resulting in a mess.
Editing an input's name to be empty and saving the group node, causes it disappear entirely from group node and the group node editor.

Steps to Reproduce

Minimal workflow using a note and two grouped KSamplers

For anyone facing this issue: Using frontend v1.8.8. works as expected
→ I just appended --front-end-version Comfy-Org/[email protected] to Comfy's startup arguments in run_nvidia_gpu.bat

Reproduction Steps:

1. Open a new blank workflow
2. Add 2 of the same node to the workflow
3. Create a group node containing those 2 identical nodes
4. Right click group node to open node right-click context menu
5. Click Manage Group Node in the node right-click context menu
6. In the Manage Group Node dialog, uncheck the Visible checkbox for one of the inputs belonging to one of the 2 identical nodes
7. Export/save the workflow
8. Reload the page or open a new workflow tab
9. Load the saved workflow
10. Observe that the hidden inputs are no longer hidden, despite the Manage Group Node dialog indicating that they are. On ComfyUI_frontend@=<1.8.8, the hidden status persists as expected.
