I'm using 2.6.2b. After I edited the default thanks email message, even though they don't show in the editor or in the database field, an extra pair of breaks is added after every end of paragraph tag except the last. This makes the email display with 3 lines between each paragraph.
What's in the config:
<p>[FIRSTNAME],</p>
<p>Thanks for registering for [EVENT_NAME] to be held on [EVENT_DATE]!</p>
<p>We have your details as follows:</p>
<p>[NAME]<br />[CONTACT_DETAILS]<br />[ORGANIZATION]</p>

<p>Sincerely,</p>
