I think any reasonable solution should look efficient and clean to the user.

This doesn't seem to have any effect, though. Adding

      (when (eq ?\n (char-after (overlay-start ov)))
        (let ((inhibit-modification-hooks t))
          (put-text-property (overlay-start ov) (1+ (overlay-start ov)) 
'cursor t)))

to the end of company-pseudo-tooltip-unhide creates no change in the 
behavior.
