#009305: Custom tags not showing

Hi there,
after updating to ezpublish 3.8.5, I noticed that <br> withing custom tags no longer show correctly.
http://www.cpl.it/azienda/contatti <-- this page uses a custom tag for each paragraph, now it shows everything on a single line instead of rendering <br> at the end of each line. The template gets parsed because looking at the code I can see <p class="interlineaminore">. The custom tag is paragrafo-stretto
This is my content.ini.append.php (available in public and admin siteaccess).

<?php /* #?ini charset="iso-8859-1"?

Create a custom tag for a paragraph. In the paragraph write some lines separated by carriage returns. eZ will render them without <br>.
