Describe the issue

I'm tryna customize bootstrap for a website I'm building but I've came accross an issue:
When I import bootstrap's CSS normally, downloading or from a CDN I can use the .bg-dark class, but when I use SCSS and import bootstrap's SCSS, the bg-dark class isn't created.

That makes a big issue on my website as my navbar is using this class.
I've searched in my generated css (ctrl+f) "bg-dark" and did not found the class.

Here is the scss part where I import bootstrap:

@import "../node_modules/bootstrap/scss/functions";


$gold: #ffcc00;
$red: #e72020;
$yellow: #c99e12;
$blue: #1e90ff;
$dark-blue: #093085;
$hestia-blue: #3b4776;
$lighty-hestia-blue: #b2d3fa;
$green: #288509;
$greeny: #9BA841;

$theme-colors: (
    "primary": $gold,
    "secondary": $hestia-blue,
    "tertiary": $lighty-hestia-blue,
    "success": $green,
    "info": $blue,
    "warning": $yellow,
    "danger": $red,
    "blue": $blue,
    "red": $red,
    "yellow": $yellow,
    "gold": $gold,
    "hestia-blue": $hestia-blue,
    "light-hes-blue": $lighty-hestia-blue,
    "green": $green,
    "greeny": $greeny,
    "dark-blue": $dark-blue,
);

@import "../node_modules/bootstrap/scss/variables";
@import "../node_modules/bootstrap/scss/variables-dark";

@import "../node_modules/bootstrap/scss/bootstrap";
@import "../node_modules/bootstrap/scss/utilities";

// rest of customization after those statements

Reduced test cases

I cannot do a reduced test case as I cannot seem to make bootstrap work with customization with SCSS on codepen and don't know how to make one that works either.

I found a workaround using bg-secondary-subtle to do the same thing, but it'll be better if the bg-dark class worked.
