Fix comment_order for single page comment threads.

The old comment pagination logic had a separate block for comment threads that
appeared on a single page. After the refactoring in [34561], all comment
pagination logic is unified.

This change ensures that 'comment_order' is respected in all scenarios.

Fixes #8071.
