[REV] website_slides : Adjust container to contain the full course name

This reverts commit 27a1ccc8 which fixed the container height
when course name was too long. It added a 'visibility: hidden'
style which caused an issue on the course left bar where the
progress bar and completed tag are located next to each other.
