Mention does not work properly when html tag is put before mention prefix.

[wadakatu]

Mention extension does not work when I put html tag before mention prefix which is '@' .
Seemingly, there is no <a> tag in the converted result.

configuration

 $environment = new Environment([
                'html_input' => 'escape',
                'mentions' => [
                    'username' => [
                        'prefix' => '@',
                        'pattern' => '[a-z\d](?:[a-z\d]|-(?=[a-z\d])){0,38}(?!\w)',
                        'generator' => config('app.url').'/user-info/%s',
                    ],
                ],
            ]);

            $environment->addExtension(new CommonMarkCoreExtension);
            $environment->addExtension(new MentionExtension);

            return new LeagueConverter(new MarkdownConverter($environment));

example markdown

<p>test</p> @wadakatu

expected output

<p>&lt;p&gt;test&lt;/p&gt; <a href="https://test/user-info/wadakatu">@wadakatu</a></p>

actual output (no <a> tag.)

<p>test</p> @wadakatu

Could you tell me whether or not this behavior is intentional?
Is there any way to accomplish expected output ?

Thank you.

Hi there!

According to the CommonMark spec, your example Markdown input contains an HTML block (type 6) which includes @wadakatu as-is. With HTML blocks:

Everything until the next blank line or end of document gets included in the HTML block. So, in the [...] example, what looks like a Markdown code block is actually part of the HTML block, which continues until a blank line or the end of the document is reached

The behavior you're seeing will happen with any type of Markdown that co-exists on the same line as the HTML, like in these examples.

To accomplish the expected output, you'll need to move the mention out to a separate line like this:

<p>test</p>

@wadakatu

Or use an Raw HTML inline (instead of an HTML block) by starting the line with some non-HTML like this:

This is a <p>test</p> @wadakatu

Thank you for your prompt answer.
I think that your first suggestion is suitable for me.

Best Regards.
