An issue with electric mode

[Angelo Graziosi]

Maybe this is not an issue but just e feature..

In the init.el I have

(electric-pair-mode 1)

and in an .adoc buffer (it is an Asciidoctor document which Emacs processes in 
Fundamental mode) I have this text:

_function_ ends (with `return` or with `}`)

Before this line the electric-pair-mode does not work. In short the '(' is 
matched with the '}' (in violet) so the last ')' is considered unmatched.

Is this the right behavior?

Thanks,
  Angelo.
