Hello, recently I switched from maint to master (release_8.3beta-1091-g96c533) and noticed that org-block face defined in my theme does not work anymore.
What could be of some help is that when I type <s TAB, I see a code block #+BEGIN_SRC #+END_SRC with the correct background face in the block specified in my theme. But, when I type in a language (typing one non-blank character after BEGIN_SRC is enough), the face inside the block changes to the Emacs default one. e.g. #+BEGIN_SRC python #+END_SRC I got the same behavior with emacs -q. Regards, Michal
