Multi-character Emoji not compatible with copy and paste

Repro:

• Send or receive:👌🏽👌🏾👌🏿 <-note that some of these emoji are multi-character.
• Copy those emoji to clipboard.
• Paste those emoji.

Expected: 👌🏽👌🏾👌🏿
Observed: 👌🏽👌🏽👌🏽 (only the first character of each emoji is preserved)

I think we're copying to the clipboard as the "name" of the emoji (e.g. ":ok_hand:"), not the emoji itself.

More good test data:

Yeah, interesting. I notice that there seems to be no official name for the emoji with modifiers: https://emojipedia.org/ok-hand-sign-type-6/

What if we changed the copied text to be the actual emoji? I suppose it could result in weirdness when copying from a message into the message composition text box if the system doesn't support the full emoji set... But it would give us the right behavior in this scenario, at least on my machine...
