As a user, I expect Opencast to correctly indicate in the table headers what can be clicked and what cannot
Opencast has some global CSS that determines the style of almost all tables in the UI (also the tables in the detail modals).
One of the things that currently is incorrect from a usability point of view is that all table headers are clickable (indicated by hand mouse cursor) although a lot of them don't handle the clicks.
The corresponding pull request has been merged. I therefore resolve this issue "Fixed and reviewed".
