CLIP Text Encode Bug

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

The text jumps at the beginning when the cursor is outside the node.

### Steps to Reproduce

1. Add a CLIP Text Encode.
2. Put a lot of text so the scroll will appear.
3. Scroll down at the end.
4. Move the cursor outside the node.
5. The node text jumps at the beginning.
