Research direction

Reproduce the issue in CodeEditSourceEditor 0.15.2 by creating an editor and pasting the exact long line from the report. Trace the editor's text-wrapping and cursor-layout path, then verify that the line wraps without duplicated text and that cursor movement remains correct.

Description

bug
Description

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

In this case it's this string:

* 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.
