Sorry, you both. Here's the missing piece:

(setq bidi-display-reordering nil)

This is pretty low-level var, so maybe it's not even supposed to be set 
by a user.

Sorry, see above.

Yes.

Indeed, this only happens when a suitable backend gets enabled, and 
company-elisp only works in IELM buffers in the upstream Company, not 
yet with code in ELPA. You can try

(require 'company-capf)
M-x company-capf

but that really doesn't matter, since it's unrelated to the bug and just 
indicates that the current candidate has indeed changed after you 
pressed M-n or M-p, and it's just overlay display that wasn't updated.

I saw that fix, but no change.
