May just be my laptop, or that I use Chrome, but when I hover the arrow over "Like", a bar about 3 inches wide appears below. In the very far right side of the bar, there's an emoji (the only one that appears). When I hover the arrow over it, a small blue box appears just above that I says "Angry". No other emojis appear in the bar, but I just happened to move the arrow to the left after hovering over "Angry", and small blue boxes appear as if the denote the blank space has other emojis, and what the absent emojis mean. Moving to the left from "Angry", is "Insulting", "Dislike", "Sad", "Meh", "Ad Hominem", "Verbose", "Applause", "Happy", and "Like". But, as I said, there is no actual emoji that appears within the bar other than the "Angry" emoji.
Just thought I let you all know in case others are not seeing things that are being discussed, such as tongues, and sunglasses.
