emoji-chooser: show tooltips with emoji names
It is sometimes difficult to distinguish emoji. Sometimes there are even duplicate emoji. (For instance there appear to be 2 United States flag emojis. Both are located near the bottom of the list of flag emoji.)
In these cases, I think it would be useful if the emoji chooser would show the names of the emoji, perhaps in a tooltip.
Steps to reproduce
- Start an app like gedit. Right-click in the text area and choose Insert Emoji
