Hide org-ellipsis in flip,rate mode

[souew]

In flip mode all other org headings in the tree are collapsed, which creates "..." on the each line, sometime it even leads to a line break if "..." is too close to an edge. I think it visually clutters the interface and is not necessary.
I did something like that:
(add-hook 'org-fc-review-flip-mode-hook (lambda () (setq org-ellipsis " ") (org-mode-restart)))
Which works, but it's ugly and not really a proper solution because I don't have org-fc-review-flip-exit-mode-hook to restore the settings.
