Visual issue: buttons on top of progress bar

There may be an issue with JoubelUI or H5P-Question, probably CSS related. I have not yet looked into it. If the horizontal space is small and the feedback message long enough to cause a line break, then the buttons may be put on top of the progress bar.

1. Steps to recreate the bug
   Have a look at https://h5p.org/node/117359 or create your own content type with a quite long feedback message and then make the horizontal space smaller, e.g. by resizing the window.
2. Platform you're using: Drupal, Wordpress, Moodle (version number would be helpful as well)
   Drupal 7 in the case of h5p.org, also found on Wordpress 4.8
3. Mobile or Desktop
   Desktop and mobile (depending on screen width)
4. Browser: Chrome, Firefox, Safari etc
   Confirmed on Chrome, Firefox and IE (Desktop) and Safari (mobile)
5. H5P plugin version
   Whatever you are using on h5p.org, latest version of Wordpress plugin
6. H5P content type version
   e.g. the latest version of Multiple Choice or Fill in the Blanks
7. Screenshots if it's a visual problem
