NOTHING WORKS!

### Prerequisites

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

### What happened?

I don't know what you people are doing with this frontend but nothing works properly anymore.

Group nodes? Broken!
Subgraphs? Still not usable.

### Steps to Reproduce

**Group nodes** (I know deprecated but still they used to work)

1. Select a bunch of nodes then make a group node
2. Go to manage node and change visibility of inputs and widgets
3. Group node "explodes" back into individual nodes when you click Save
4. Go back to step one because apparently save means destroy

**Subgraphs**

1. Select a bunch of nodes, make sure one of them is `TextEncodeQwenImageEditPlus` then create subgraph
2. Go to edit subgraph widgets and try to rename any of the inputs
3. You can't
4. Try finding and enabling the additional image inputs (image2, image3) I dare you to find them
5. You can't

Workspace

1. add a node
2. double click title to edit name
3. sometimes you can delete the node while rename active

Are you testing anything or just vibe coding this?

Until you can't get subgraphs to be usable please at least don't break what used to wrok.

### How is this affecting you?

Feature doesn't work as expected

### ComfyUI Frontend Version

### Browser

### Console Errors

### Logs

### Additional Context

_No response_

Start by reproducing the reported group-node, subgraph-widget, and workspace rename behaviors in ComfyUI Frontend 1.45.15 on Chrome/Chromium. Check whether group nodes remain intact after changing input or widget visibility, subgraph inputs can be renamed and revealed, and nodes cannot be deleted during title editing; add or run focused regression coverage for each confirmed failure.
