Joomla 5
Astroid 3.1.1
Template Two
..
In Category Blog view is no floating image and no image caption. In Blog Featured Article its working.
Maybe depends on that in Category Blog, the file: intro_image.php is not loading
And in the file
\libraries\astroid\framework\html\com_content\category\blog_item.php
is a "d-flex" class which must be removed to float the image.

Example here

Please check if its right.
