Select for BS5 does not handle table variants

When using BS5 table variants like "table-light", "table-dark" etc select does not draw/coloring as expected.
See example http://live.datatables.net/huhaciwu/1/edit (with and without table variant enable)

Default BS5 sets the --bs-table-bg: transparent, but when you use "table-light" then coloring is --bs-table-bg: #f8f9fa;

Tried to put "!important" behind the coloring of "background-color" in the select.css, without any effect.

Note on variants: https://getbootstrap.com/docs/5.0/content/tables/
This is what happens behind the "scenes".

@mixin table-variant($state, $background) {
  .table-#{$state} {
    $color: color-contrast(opaque($body-bg, $background));
    $hover-bg: mix($color, $background, percentage($table-hover-bg-factor));
    $striped-bg: mix($color, $background, percentage($table-striped-bg-factor));
    $active-bg: mix($color, $background, percentage($table-active-bg-factor));

    --#{$variable-prefix}table-bg: #{$background};
    --#{$variable-prefix}table-striped-bg: #{$striped-bg};
    --#{$variable-prefix}table-striped-color: #{color-contrast($striped-bg)};
    --#{$variable-prefix}table-active-bg: #{$active-bg};
    --#{$variable-prefix}table-active-color: #{color-contrast($active-bg)};
    --#{$variable-prefix}table-hover-bg: #{$hover-bg};
    --#{$variable-prefix}table-hover-color: #{color-contrast($hover-bg)};

    color: $color;
    border-color: mix($color, $background, percentage($table-border-factor));
  }
}

Reproduce the issue using the linked live.datatables.net example with and without Bootstrap 5 table variants. Start by inspecting select.css and the Bootstrap table variant documentation, then compare the selection styling under the default and table-light/table-dark cases. Done means Select renders the expected coloring for both default tables and supported table variants.
