In the forums, the 
emoji has a weird behavior. If you go to the emoji pane when making a new post, then choose the skin tone other than the gold one, then scroll down to the 
hand thing, you'll see this:
How can it be like this? This may cause weird visual bugs: 
This is not even an image. Can you fix this?
not sure what you're talking about
that isn't an image of a handshake and it's the gold skin tone, neither of those are what ten's talking about as far as i can tell
I have a feeling this is a simple thing that can be fixed, because not all emojis have skintones. I did also figure out the format the software uses to get the images
/images/emoji/apple/handshake.png?v=12
for the default emoji
/images/emoji/apple/handshake/2.png?v=12
for the skintone.
How it works is, it just has the emoji image like this, handshake.png, then for a skintone, it adds /t before .png, e.g. handshake/2.png.
I have a feeling the snap devs could just upload the images to get it to work (and looking at the url, I'm guessing it's the apple emojis). A great place to find the emoji images is emojipedia.
Every understands what you mean, there is no need to repeat yourself.
