JabRef version on

JabRef 5.0--2020-03-06--2e6f433
Mac OS X 10.15.4 x86_64
Java 13.0.2

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

Steps to reproduce the behavior:

1. ...Enter the author name field
2. ...place the cursor
3. ...strike the forward-delete key to delete the char to the right of the cursor
4. ...A dialog pops up asking if I want to delete the record.

This is inappropriate behavior when editing a field. It should only act this way when a record is highlighted in the list AND the list has focus.
