Maybe Stefan Monnier can tell us what he does in such case.

I can offer the attached, largely untested patch.  A possible
customization would then be

(customize-set-variable
 'display-buffer-alist
 '(("*Completions*"
    (display-buffer-reuse-window
     display-buffer-pop-up-frame)
    (reusable-frames . t)
    (redirect-frame-focus . t))))
