HOTFIX: added aditional check for like/dislike buttons inside ACTIVE Viewport

In certain cases (see issue #741), the like/dislike buttons would be considered IN the viewport, despite its parent elements being hidden and its DOMRect being 0 on all sides. This way, added an additional check for considering these "hidden" buttons as NOT in the Viewport.
