What should happen:
When pressing enter or clicking save should activate the gray "on hover" style on the newly created card, and display the pencil edit icon for that newly created card.
What is happening:
When creating a new card, the previously hovered card will continue to be gray and show the pencil edit icon, regardless of pressing enter or creating a new card.
