Sass compilebreak: Undefined variable $input-bg in kendo-theme-default (checkbox) after updating from v4.23.0 to v4.24.0

[sceee]

Describe the bug
After updating kendo-theme-default from ^4.23.0 -> ^4.24.0, the following Sass compilebreak occurred:

ERROR in ./src/common/kendo.scss (./node_modules/css-loader/dist/cjs.js!./node_modules/sass-loader/dist/cjs.js!./src/common/kendo.scss)
Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: Undefined variable.
   ╷
12 │ $checkbox-bg: $input-bg !default;
   │               ^^^^^^^^^
   ╵

To reproduce
Steps to reproduce the behavior:

1. Use the following code to embed kendo themes in a kendo.scss file:

@import "@progress/kendo-theme-default/scss/grid/_index.scss";
@import "@progress/kendo-theme-default/scss/spreadsheet/_index.scss";
@import "@progress/kendo-theme-default/scss/dataviz/_index.scss";
@import "@progress/kendo-theme-default/scss/editor/_index.scss";

2. Compile it using webpack with sass-loader
3. Compilebreak mentioned above occurs - I feel it is resulting from 1b9bf25

Note that the code compiles successfully in v4.23.0.

Expected behavior
Variable is defined, compile still works
