HTML form tags in code blocks are actually rendered in Opera Mobile [closed]

Question

When viewing PHP - Submit button does nothing in Opera Mobile 12.00, the

<form method='post' action='http://cogameservers.com/home/contact'>
Email: <input name='email' type='text' /><br />
Subject: <input name='subject' type='text' /><br />
Message:<br />
<textarea name='message' rows='15' cols='40'>
</textarea><br />
<input type='submit' />
</form>

section of the code not only renders the input areas, but also a working submit button. Strangely, I haven't found another question with the same effect.

Edit not by OP:

Here's what the page looks like in Opera 12 Mobile on ICS when using the desktop layout, the mobile interface and the mobile interface with Turbo disabled, respectively:

That's a browser bug that we here cannot do a single thing about. Everything Stack Exchange can do has been done. Those opening and closing angled brackets are already escaped/encoded into HTML entities. If the browser is actually rendering the HTML, that's the browser's problem.

<pre><code>&lt;?php
if (isset($_REQUEST['email']))

 {

$email = $_REQUEST['email'] ;
$subject = $_REQUEST['subject'] ;
$message = $_REQUEST['message'] ;
mail("[email protected]", $subject,
$message, "From:" . $email);
echo "Thank you for using our mail form";
}
else
 {
 echo "&lt;form method='post' action='http://cogameservers.com/home/contact'&gt;
Email: &lt;input name='email' type='text' /&gt;&lt;br /&gt;
Subject: &lt;input name='subject' type='text' /&gt;&lt;br /&gt;
Message:&lt;br /&gt;
&lt;textarea name='message' rows='15' cols='40'&gt;
&lt;/textarea&gt;&lt;br /&gt;
&lt;input type='submit' /&gt;
&lt;/form&gt;";
}
?&gt;
</code></pre>
