Steps to reproduce the issue

<?php echo HTMLHelper::_('bootstrap.startAccordion', 'accordion-test'); ?>
<?php echo HTMLHelper::_('bootstrap.addSlide', 'accordion-test', Text::_('TEST'), 'test-collapse', 'test'); ?>
   <h1>TEST-ACCORDION</h1>
<?php echo HTMLHelper::_('bootstrap.endSlide'); ?>
<?php echo HTMLHelper::_('bootstrap.endAccordion'); ?>

When you now go to the view articles, you see the closed accordion.
Click on the accordion to open it.
The accordion opens.

The accordion now closes although it should stay open.
