- do not display creator buttons until hovered
- make last name have flex-grow priority over first name
- removed inline margins of rows
- removed extra padding from icons
This makes it more likely that the creator name will be displayed
fully without ellipsis until it is hovered. When the buttons are
displayed on focus or hover, the last name tries to remain
unellipsized as long as the first name is still visible after buttons
appear. If the first name is too short, both names will be ellipsized.
