Describe the bug

I got this error log when I run my unit test (using vitest):

TypeError: Cannot read properties of undefined (reading 'matches')
    at setColorSchemeAttribute (file:///Users/macbook-giovannidejan/VSCodeProjects/iamdejan/react-iam-dashboard/node_modules/.pnpm/@mantine+core@file+..+mantine+packages+@mantine+core_@mantine+hooks@file+..+mantine+packages+_74wiwvogszovmx2h66rqol7oqu/node_modules/@mantine/core/src/core/MantineProvider/use-mantine-color-scheme/use-provider-color-scheme.ts:5:138)

Upon investigating with git bisect, I narrow down the bug to commit bad9bc5f0. I wonder if there's anything that triggers the error.

Thank you.
