Widget doesn't work with translated taxonomies

Problem/Motivation

Widget at node form doesn't work with translated taxonomies. Uses the default language instead. The problem occurred in this version and the previous one 8.x-1.2 didn't has this problem.

Steps to reproduce

1) Create taxonomy term
2) Translate it
3) Create an entity reference field for a content type
4) Select as reference type vocabulary the taxonomy term you created earlier
5) Set cshs as the widget of the field at "Manage form display"
6) Widget works properly when the site is at default language, but when the site is at a secondary language the widget keeps fetching default's language taxonomy terms
