purity IV on J 5.0.0: pagebreak does not work

hello,
as title, on J5.0.0 the peagebreak does not work, with purity iv.
the page show only a line, but no page break.

same site, with cassiopeia template, works fine.

You can open file: /templates/ja_purity_iv/html/com_content/article/default.php

Look for this line of code:

<?php echo HTMLHelper::_('content.prepare', $this->item->fulltext); ?>

change it to:

<?php echo HTMLHelper::_('content.prepare', $this->item->text); ?>

soled. many thanks
