### Bug description

Authors and affiliations in the YAML header aren't printed when there's no title defined.

### Steps to reproduce

```
---
format: html
author:
  - name: Norah Jones
    affiliations:
      - ref: cmu
      - ref: chicago
affiliations:
  - id: cmu
    name: Carnegie Mellon University
    city: Pittsburgh
    state: PA
  - id: chicago
    name: University of Chicago
    city: Chicago
    state: IL
---

Foo
```

### Expected behavior

I'd expect the output to show the author and her respective affiliations.

### Actual behavior

The example above prints `Foo` only.

### Your environment

IDE: RStudio 2023.03.1+446
OS: MacOS Monterey 12.3.1
