// However, this interferes with the use case of placing a list on other components. For example,
// the bottom sheets container color is `md.sys.color.surface-container-low`. Instead, allow the
// list to just display the colors for its background.
// list-item-leading-icon-size
// Match spec, which has list-item-leading-icon-size of 24px.
// Current version of tokens (0_161) has 18px.
