Current behavior

In Angular-cli.json file, instead of pointing to bootstrap css, if it is pointed to bootstrap sass, amexio components are not rendering properly. In angular-cli.json i have included
"styles": [
"assets/styles/vendor.scss",
"assets/styles/styles.scss",

vendor.scss consist of
$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/";
@import
'~bootstrap-sass/assets/stylesheets/bootstrap';

By this way amexio components are not rendering properly. Even after including bootstrap sass do i need to still include bootstrap css

Expected behavior

Components should render properly with bootstrap sass

Minimal reproduction of the problem with instructions

For bug reports please provide the STEPS TO REPRODUCE and if possible a MINIMAL DEMO of the problem via
https://plnkr.co or similar (you can use Our Amexio Plunker as a starting point: http://plnkr.co/edit/M9AeGH?p=info)

What is the motivation / use case for changing the behavior?

I am using amexio component for developing production application, and since we are using bootstrap 4 which is made up in sass(scss), i only want to point to bootstrap sass like this in a scss file and include this scss file in angular-cli.json
$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/";
@import
'~bootstrap-sass/assets/stylesheets/bootstrap';

Which Angular CLI Version are you using ? As older versions of CLI needed to set a explicit flag for SCSS
ng set defaults.styleExt scss . We have reproduced the issue and set the angular-cli.json to

"styles": [
"../node_modules/bootstrap/scss/bootstrap.scss",
"assets/styles/styles.scss",
]

And Found no issue's.
Angular CLI Version : 1.4.3
