- Fixes #1363

## Checklist

- [x] Fails when test case legitimately fails
- [x] Retries when test case fails with "codewindow unresponsive"
- [x] Succeeds when test case succeeds
- [x] I have added
[tests](https://www.cursorless.org/docs/contributing/test-case-recorder/)
- [x] I have updated the
[docs](https://github.com/cursorless-dev/cursorless/tree/main/docs) and
[cheatsheet](https://github.com/cursorless-dev/cursorless/tree/main/cursorless-talon/src/cheatsheet)
- [x] I have not broken the cheatsheet
