### Bug description

If the first paragraph of a page contains formatting (bold for example) the listing layout breaks. I tried with a page (among a number of other pages without formatting) that contains some bold first paragraph like so:

```md
---
title: "Test1"
---
**Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin maximus turpis id neque pharetra, ut vehicula augue sagittis. Duis pellentesque dolor vel diam imperdiet lacinia.**

Nulla facilisi. Morbi placerat faucibus mauris a luctus. Donec pellentesque mauris auctor tortor laoreet maximus. Maecenas ac risus in turpis suscipit euismod. Cras id congue nibh. Donec efficitur risus nec velit convallis consectetur. Morbi tincidunt non urna non ornare.
```

In a grid listing the cards are stuck in two columns. In a blog style the "columns" break.

I am using Quarto 1.2.157 on Mac OS 12.6.
