I understand that an initial blank line in an HTML block enables markdown mode, but I would not expect later lines to do this, for example with this input:

# Hello world

<div>
    <p>First paragraph</p>

    <p>Second paragraph</p>
</div>

I get the following output:

<h1 id="helloworld">Hello world</h1>

<div>
    <p>First paragraph</p>

<pre><code>&lt;p&gt;Second paragraph&lt;/p&gt;
</code></pre>

</div>

If the rule is that any blank line in HTML blocks enable markdown mode (for the remaining content), it means that we cannot visually group elements, which would be a loss for readability.

Using v6.3.2 installed via homebrew.

Using --compatibility does not change the above behavior.
