Comment to a photo when made in the photo page itself - not seen unless the page is refreshed one or more times
When a comment is made to a photo by directly accessing it from the Recent photo Masonry display or an Album, and not from the Stream, the comment is not immediately seen unless the page is refreshed once or more than once. When a comment is made to a photo from the Channel home or Network stream it shows up instantly. I have tested this with core-6.4RC
Similarly "Like" or "Dislike" done is also not seen immediately unless the page is refreshed. In fact same user can Like and Dislike BOTH on the same item.
