subgraph editor/functionality is broken

### Prerequisites

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

### What happened?

version: v1.45.20

issues:

1) the subgraph editor is not functioning. i can reorder inputs in the sidebar but it doesn't change on the main canvas.

2) i have a subgraph for a wan2.2 2 sampler setup. i can connect the total sample count for sampler 1 but it doesn't allow a connection to the sampler 2. that's programmaticly broken parameter recycling. who coded that crap?

(i really don't like bad open source. too many cooks ruin the soup. get one cook in there and fix that module properly.)

### How is this affecting you?

Feature doesn't work as expected

### Additional Context

_No response_

No files, tests, or reproducible steps are provided. Start by reproducing both reports in ComfyUI Frontend v1.45.20 on Firefox: reorder subgraph inputs and try connecting total sample count to both samplers. Done means sidebar ordering is reflected on the canvas and the intended sampler connections work, with console errors or logs captured if they occur.
