I just tried to assign one tag to several selected photos. So I selected eg two photos and then in the "Comments/Tags" side tab clicked on the tag I wanted to assign. The result was, that only the first of the two photos got the tag assigned. However if I use the contex menu (right klick over one of the two selected photos) and then assign the tag both photos get it. The same is true for removing the tag.
