the node search window is stuck in the new version

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

it was fluent to search for the needed node

### Actual Behavior

now it takes a while to respond to the input

### Steps to Reproduce

double click the blank aera and the search window pop up. I input the title of a node search and there is no response for a whilte before the text showing up

### Debug Logs

```powershell
not apllicatable
```

### Other

_No response_

No source file or test is named. First reproduce the delay by double-clicking the blank canvas and typing a node name, then locate the node-search UI entry point and determine where input handling becomes slow. Done means the search responds promptly and displays the entered text without the reported pause.
