Code Review

This pull request updates GameListPopupMenu.java to dynamically apply a "selected" CSS pseudo-class to the game list items based on their selection state. To support this, the rootPane variable was promoted to an instance field. The review feedback points out a minor syntax error where a double semicolon was introduced in the rootPane field declaration.

Important
