Fix: Correct typo in comment (#18361)

This pull request contains a couple of minor documentation fixes.

- Corrected a typo from `predicable` to `predictable` in a comment for
`DarkModeStrategy`.
- Applied minor formatting to a comment in a test file.

These changes help improve code clarity and maintainability.
