Copying text messes up the data, so copy & paste is broken

@tiensonqin is already working on this.

Since Jun 19, 2026.

### Search first

- [x] I searched and no similar issues were found

### What Happened?

When i copy selected text, it gets changed!

becomes:

```
- deinstalliert. man wird nach dem stant angfbote geld auszugeben



- nach dem eigentlichen spielfn werbung
```

and that can not be pasted into Logseq OG!

There are 3 additional lines added with 2 whitespaces.

### Reproduce the Bug

1. select multiple lines of text
2. copy or cut
3. paste into text editor

### Expected Behavior

the text should be copied exactly as-is and not get changed in any way

### Screenshots

Demonstration: https://youtu.be/owPKO_OD5d4?si=SHqwqnoeOAz7xrGa&t=49

Since i can't select the text or use the copy button, here are screenshots of the raw block data. The text itself looks fine.

### Files

### Browser, Desktop or Mobile Platform Information

NixOS 25.11.10684.8fd9daa3db09

### Additional Context
