<p><br>text <code>code</code> <strong>bold</strong></p>
<p>more text</p>

Currently in your browser:

  • But why use <br/> at all? I think that generally, most markdown is disabled if it has another "command" above it, like --- requiring an empty line in order for it to be rendered as a horizontal line, but is this a problem? If you just leave an empty line instead of the br tag doesn't it work?

This is the expected behavior according to the Commonmark spec (link against the reference implementation).

The <br/> constitutes opening an HTML block , which (for most start conditions) is only terminated by a blank line. In the Commonmark reference spec for HTML block, the appropriate condition here is number 7.
