Please describe the bug

The following Markdown is not rendered properly:

Line 1

<br />
Line 2

From CommonMark Dingus, it would output:

<p>Line 1</p>
<br />
Line 2

Note: "Line 2" is a text node and is not wrapped in <p>. This is expected.

Do you see any errors in console log?

No.

How to reproduce the issue?

Bot send the following Markdown message.

Line 1

<br />
Line 2

What do you expect?

It renders with both "Line 1" and "Line 2".

<p>Line 1</p><br />Line 2

What actually happened?

It renders without "Line 2".

<p>Line 1</p><br />
