JabRef 5.1--2020-04-20--bc57d22
Windows 10 10.0 amd64
Java 14.0.1

I think this is a regression in the current dev version - it is not a big issue to me, but I reckon this is not intended behaviour.

1. Create a new item in JabRef which contains some Latex formatting, e. g. make parts of the title italic by using textit{} or by addind diacritics
2. Note, that the formatting is "ignored" in the main table, i. e. the formatting code is displayed instead of displaying the words in italic/with diacritics
3. The entry preview, on the other hand, translates the formatting code correctly and displays the words in italic/with diacritics

An example is attached.
