Hmm...then, it might be necessary to wait a little before trying to
bring back the focus.  Unlike Evince, Okular is called with normal
`TeX-run-discard' hook and runs asynchoronously, so the function
`select-frame-set-input-focus' in question might run too early, when
okular is not yet ready.

If this speculation is right, this kind of treatment is valid for okular?
    (when (and TeX-view-keep-focus
               (string= name "View"))
      (sit-for 0.3)
      (cond ((fboundp #'select-frame-set-input-focus)
             (select-frame-set-input-focus (selected-frame)))
            ((fboundp #'x-focus-frame)
             (x-focus-frame (selected-frame)))
            ((fboundp #'focus-frame)
             (focus-frame (selected-frame)))))))

OK, then let's take this approach about this aspect.
