Steps to reproduce the issue

Use any content plugin that implements onContentPrepare() in a weblink‘s description (you know, stuff like {toc}). Then open the category page.

Expected result

The content plugin should do their magic.

Actual result

The content plugins don’t do anything with the weblink‘s description.

System information (as much as possible)

Joomla 5

Additional comments

Can easily be fixed by changing the line

<?php echo $item->description ?>

to

<?php echo \Joomla\CMS\HTML\HTMLHelper::_('content.prepare', $item->description); ?>

in com_weblinks/category/default_items.php. In revision 6738e6e, this would be in line 234.
