node2.0 does not respect viewport fps but noodle link does so link and node window not sync causing mismatch, lag behind

### Prerequisites

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

### What happened?

set viewport fps to 1 and pan screen. node 2.0 and 1.0 behave differently.

strangely setting maximum fps to 0 fixes desync link rendering issue.

### Steps to Reproduce

### How is this affecting you?

Crashes ComfyUI completely

### ComfyUI Frontend Version

1.47.11

### Browser

Chrome/Chromium

### Console Errors

```javascript
at 1 viewport fps node 2.0 node window is snappy but node 1.o is very slow
```

### Logs

```shell

```

### Additional Context

_No response_

Start by reproducing the issue in Chrome/Chromium with viewport FPS set to 1 while panning, comparing node 1.0, node 2.0, and noodle-link rendering. Investigate the frontend rendering path responsible for viewport frame limits; done means node and link windows remain synchronized without lag or a ComfyUI crash.
