Chosen is no longer applied after update to BEF 4 (Block´s)

As described in the related issue - the same with blocks:
After I have updated to version 8.4 of the BEF, chosing no longer works.

A simple block (generated by a view) (show all nodes) with a taxonomy exposed filter shows

a) Basic Filter works
b) Version 8.3 works
c) Version 8.4 (8.x-4.0-beta1) does not work

See attached settings and screenshots.
