When did Color Look up Table stop to work?

I am presently using latest darktable-git.
The Color Look up Table module does not
behave as it should (according to the docs).
Among other things, its color picker loses
focus after a single click in the main window.

v. 2.6.2 seems OK.
v. 2.7.0 (git) is not OK.

Have fun!
