This is not a filesystem issue, the filesystem is behaving correctly. In order to persist data to disk (on _any_ filesystem), the application must call fsync(). This is part of the POSIX spec. By not calling fsync(), LibreOffice is basically _telling_ the filesystem that it is not important to retain this file in the event of a power outage.
