Expected behavior

2 paragraphs should show up. (Maybe)

Actual behavior

For Aztec edited posts with hardcoded HTML (below), the Post List shows both paragraphs.

<p>Paragraph 1</p>
<p>Paragraph 2</p>

For Gutenberg, with 2 paragraph blocks and same content, the Post List only shows the first paragraph and with a blank space below.

Steps to reproduce the behavior

1. Create a post in Gutenberg.
2. Add 2 paragraph blocks with one-line content.
3. Publish the post.
