    text: Make Emoji insertion work properly
    
    We are now getting focus-out and focus-in events
    when the Emoji chooser is shown and hidden, and
    this is causing the text to select-on-entry before
    inserting the Emoji, which then deletes the selection.
    
    Avoid this by saving and restoring the selection
    when presenting the Emoji chooser.
