Linebreak and text vanish in HTML label

[kannes]

What is the bug or the crash?

I tried to create some fancy labels for a vector layer with HTML formatting but some parts are not displayed, parts of my text are vanishing.

On the left is my label expression editor open, you can see the intended rendering in the preview.
On the right is one such label in a map canvas.

Steps to reproduce the issue

1. Use this as a label for a layer: foo<br>bar<span style="color:red">baz</span>
2. Enable HTML rendering for the label
3. Look at such label in the map, it reads "foo baz" with "baz" shown in red, "bar" is not shown although space seems reserved for it

Additional context

If I use <p></p> instead of a <br> or <br />, it looks as intended.
