Emai body field unusable

After your update to 2.0.3 my inputfield for email content looks like this:

<div style="background: #f5f5f5; color: #333; font-size: 14px; line-height: 20px; font-family: Arial, sans-serif;">
<div style="width: 600px; margin: 0 auto;">
<div class="header" style="border-bottom: 1px solid #ddd; padding: 20px 0; text-align: center;"><strong style="font-size: 20px;">{site_name}</strong></div>
<div class="content" style="padding: 10px 0 40px;">
<p style="font-size: 14px; line-height: 20px; color: #333; font-family: Arial, sans-serif;">Hallo {user_name},</p>
<h4 style="font-size: 14px; line-height: 20px; color: #333; font-family: Arial, sans-serif;"><em><span style="color: #333333; font-family: Arial, sans-serif;">Verifieer uw account door op onderstaande link te klikken</span></em></h4>
<p style="font-size: 14px; line-height: 20px; color: #333; font-family: Arial, sans-serif;"><a class="btn" style="color: #fff; border-radius: 3px; text-decoration: none; background-color: #51b3ff; padding: 10px 20px; font-size: 14px; font-family: Arial, sans-serif;" href="{ac_activaton_url}">Activeer account</a></p>
<p>Succes</p>

</div>
<div class="footer" style="border-top: 1px solid #ddd; padding: 20px 0; clear: both; text-align: center;"><small style="font-size: 11px;">{site_name} - {site_description}</small></div>
</div>
</div>

Bit hard to proces.
