Description
Problem
When typing an inline reaction (+:+1:, for example, to add a thumbs-up to the prior response from the keyboard), the inline reaction is only sent if the emoji encompassed in the colons is converted to emoji. If you type +:glad:, the emoji picker menu will open, and the correct emoji will show up in the picker, but unless you hit tab to select an emoji, then the message will simply be sent as another message in the chat.
Expected Behavior
Typing +:+1: should add a reaction to the prior message, regardless of whether or not it was replaced with the actual thumbs-up emoji.
In searching some other issues, I found #2838, which seems to be related to the auto-conversion of emoji-formatted messages like :glad: to 😃. It was closed as a dupe of #2802, which seems to relate to converting things like :) to 😃. There may be a deeper issue / question here related to this replacement.
