🐞 Incorrect text wrapping on long lines

### Description

At least some strings seem to produce incorrect text wrapping on long lines.

In this case it's this string:

```md
* If the script includes the string `require(` anywhere in it, an export statement (`export { main };`) is appended to the script and it's compiled and bundled using esbuild.
```

### To Reproduce

1. Create an editor
2. Paste in the above long line of text

### Expected Behavior

The text should wrap without showing duplicated portions of the line

### Version Information

CodeEditSourceEditor: 0.15.2
macOS: 15.7.4
Xcode: 26.2

### Additional Context

_No response_

### Screenshots

You can see in the screenshot below that the text ‘esbuild’ is partially duplicated.

And in the screen recording you can see how the cursor behaves.
