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)?

This is such a weird fix! Good work finding it!

It isn't weird, just sloppy: QT6 seems to be handling this specific tag incorrectly when it presents with HTML void element syntax as defined in section 8.1.2.1 of the HTML 5 standard, which specifies that the slash is allowed but optional. It's hard to say whether this actually constitutes a QT bug without checking the documentation to see whether it really wants HTML or XHTML, since XHTML does require the slash.
