Doesn't work on certain sites (example)

[psarno]

I'm running v0.7.6 on Firefox 86.0.1.

The extension refuses to apply to certain elements on some sites in default (stylesheet processor). I can usually fix this by switching to another mode (simple CSS, or as a last resort, invert).

However, on some sites it still will not override, such as:

On this page, going into the browser's inspector and disabling the following rule allows the removal of the white background:

:root { --background: #EFEFEF; }

All three modes, including invert, do not affect this. Am I missing something?

On this particular website offending CSS rule seems to be

html {
    background-size: 22px 22px;
}

And it works good for me with Invert. Thanks for the report, I should probably somehow handle background-size.
