Fix horizontal scrolling in datails panel
Steps to reproduce:
- Create catalogue
- Add two courses
- Select a course, change one of the text fields ("Lernziele", "Lerninhalte", ...) to a really long string and apply the change.
- Select another course
- Reselect the course with the long string
Expected result:
details Panel should have no vertical scroll bar. The regarding text input field should have 100% of the container's width and hide the overlong string instead (the same way, as it does before applying the long string).
Actual result:
The text input field resizes to fit the contained string, all other input fields are scaled, too, and the whole panel has a vertical scrollbar.
