♿ Emoji accessibility: show name/description when hovering #2058

Is your feature request related to a problem? Please describe.
When hovering on the emoji list, there is currently no description or name of the emoji selected. It makes it difficult to know what emoji we are using and to reuse it easily. This is a problem for accessibility and for users who are not familiar with all emojis.

Describe the solution you'd like
Either:

• Show a small tooltip when hovering (ex: with the title property), or
• Display the emoji name all the time (similar to how Tchap displays it).

Describe alternatives you've considered
Currently, the only way is to guess the emoji name or try it in the editor, which is not practical.
