Reproduce Steps

Given the following Markdown:

> [!NOTE] Hugo

> [!NOTE] _Hugo_
> The world’s fastest framework for building websites

> [!NOTE] **Hugo**

> [!TIP] **Hugo** FixIt

and the following render-blockquote-alert.html

{{ warnf "%s\t%s" .AlertTitle .Text }}

Actual results is .AlertTitle lost the trailing > and .Text in a start <p> without a closing tag:

WARN  Hugo      <p>
WARN  <em>Hugo</em      <p>The world’s fastest framework for building websites</p>
WARN  <strong>Hugo</strong      <p>
WARN  <strong>Hugo</strong> FixIt       <p>

Expected results (complete .AlertTitle and .Text):

WARN  Hugo      <p></p>
WARN  <em>Hugo</em>      <p>The world’s fastest framework for building websites</p>
WARN  <strong>Hugo</strong>      <p></p>
WARN  <strong>Hugo</strong> FixIt       <p></p>

BTW, if content body of alert is empty, .Text return nil seems better.
