[~~help~~ workaround found] insert a single line break in html (Qt6 RichText) (lemmy.kde.social)

Hello! I'm writing my application in QML, and inside a TextArea formatted with RichText I want to display this:

a header

(an empty line)

another header

my first thought was to go with a <br> tag, but it has a problem: it creates 2 empty lines, don't know why. so doing this

<h1>hello</h1>
<br>
<h2>world</h2>

produces

hello

(an empty line)
(an empty line)

world

I tried using the <pre> tag:

<pre>
</pre>

but no empty lines were displayed

the only working workaround was to use a non breaking space &nbsp;, but being it a TextArea, the user is able to edit the text, and so there would be a "rogue" space instead of an empty line. How can I display just a single line break between two headers (or even paragraphs, but in my case the header is needed)?

replying to @ono@lemmy.ca as the direct reply loops forever:

thanks for the answer! I already tried an empty paragraph <p></p> but it gets stripped out by the textarea as soon as I assign it to the text property: if I print the text right after it has been modified, the empty paragraph is gone. the same goes for `` or &lt;[/]p>
