Subject: 28.0.50; defcustom with :local t doesn't set the variable
Date: Fri, 27 Nov 2020 16:54:08 -0500

(progn (defcustom myvar 1
         "Disc."
         :local t)
       myvar)

returns nil, but I expect it to return 1.

(progn (defcustom myvar2 1
         "Disc.")
       myvar2)

returns 1.

This should already be fixed on emacs-27 and more recent master.
If it isn't, please reopen.
