The 'create playlist' function on this site is great, except for one annoyance:
You have to refresh the page you are currently viewing to get an up to date version of what if any playlists a video already belongs to.
So, if you have a bunch of tabs open and have already added or removed that video to a playlist via another open tab, you don't get an up to date view on that until you refresh the page you are currently viewing.
Something similar happens when favoriting performers. If you already favorited or unfavorited a performer in another open tab, the act of favoriting or unfavoriting them again will actually have the opposite of effect of what the animation is showing you is happening.
