The dropdown buttons appear to have customized the background color but not the text color. This leaves the text color at `color: buttontext`, and this color value changes with macOS Dark Mode. This is probably also why clicking on any of the buttons causes the text to vanish during the click. It's turning white, because the default for an active button is `color: activebuttontext`.
