Background color in dark mode is is not applied

[qui8t]

I am trying to set the background color for dark mode, and I'm following this documentation:

https://docusaurus.io/docs/styling-layout#styling-your-site-with-infima

I assume you can set the background color using:

--ifm-background-color: #000000;

This setting works fine for:

:root {
  --ifm-background-color: #ebebeb;
}

on the Docusarus documentation also works fine for:

[data-theme='dark'] {
  --ifm-color-primary-lightest: #000000;
}

Light theme works fine my website, but dark theme does not work on my website. Basically, the background of the dark theme, regardless of the color I set, is always set to the default color.

Please create a repro, it's really hard to help without it
