Preview not configurable

[bernhard-kleine]

JJabRef 5.0-dev--snapshot--2019-01-23--master--c6a1fcbe3
Windows 7 6.1 amd64
Java 1.8.0_201

• [+ ] I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Steps to reproduce the behavior:

1. Open jabref and select an entry in the maintable
2. press ALT-2 twotimes to show entry preview
3. Goto OPTIONS->PREFERENCES->ENTRY PREVIEW
4. Select e.g. BIOLOGICA and view it in TEST
5. double click BIOLOGICA and
6. surprisingly you are back to the default preview
