### Bug description

The following document:

```
---
title: "<div style='zoom:75%;'>min-reprex</div>"
format: html
editor: visual
---
```

yields this warning:

```

  output-file: quarto_bug_warning_reprex.html
  standalone: true

  title: '<div style=''zoom:75%;''>min-reprex</div>'
  editor: visual
  
[WARNING] This document format requires a nonempty <title> element.
  Defaulting to 'quarto-input90370470' as the title.
  To specify a title, use 'title' in metadata or --metadata title="...".
Output created: quarto_bug_warning_reprex.html
```

HTML tags in the `<h1>` title (within the <body>) are useful, for example, it makes it really easy to add an image above the title, and additional flexibilities of course.

However, quarto yields a warning (and also the html's title is influenced by quarto's behavior).

I suggest that quarto parse html tags and apply them in the body (as it currently does), but for the tab's title (the `<head><title>...</title></head>` use a parsed version without the html tags.
