Description

When the cursor is in a paragraph and the next paragraph contains a link (or any inline element that wraps the entire text content), pressing ArrowDown bypasses that paragraph and lands in the one after it.

Steps to reproduce

1. Create a new post with the following content:

<!-- wp:paragraph -->
<p>a</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><a href="#">a</a></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>a</p>
<!-- /wp:paragraph -->

2. Place the cursor at the beginning of the first paragraph.
3. Press ArrowDown.

Expected behavior

The cursor moves into the second paragraph (the one containing the link).

Actual behavior

The cursor skips the second paragraph and lands in the third.

Environment

Reproducible in Chromium, Firefox, and WebKit.
