Modified theme colors map can not change color of some components
Created by: ysds
From my comment: https://github.com/twbs/bootstrap/issues/27712#issuecomment-444167717.
About a way of changing the theme colors, the document explains as: https://getbootstrap.com/docs/4.1/getting-started/theming/#modify-map
But, it actually is incorrect after #27378.

$theme-colors: (
"primary": green
);
