Reference method of reference field switches to first available in list if previously set to default

Problem/Motivation

The reference type settings of a entity reference field are constantly changing from default to another option.

Steps to reproduce

See screencast from this ticker:

Proposed resolution

I guess this is an issue, where other reference methods get selected when the currently chosen reference method is "default" in the database. This seems to be a selection issue of the default value in the widget. Whatever method is sorted first in the selection list gets selected.
