[BUG] Mantine example breaks the moment I add light-dark: _______ to CSS / SCSS file

[kylanhurt]

What happened?

Created the --with-mantine repository from scratch then tried to copy over the Mantine UI example for Sidebar, including the SCSS file. It looks like using the light-dark(______) function in CSS breaks the build. It renders a 🔴 ERROR | Cannot read properties of undefined (reading 'input') error (see below).

Considering that the light-dark method is supported in all major browsers I believe it should work in Plasmo!

Here is a repository to reproduce the issue:
