The problem is the lack of blue highlighting. When you click on a menu item in a system with the Breeze theme, the text turns white, while the background turns blue. Since the blue highlighting isn't appearing anymore, the text appears to (mostly) vanish (really it turns white on a slightly off-white background). That same highlighting is missing when hovering over menu items.
