Theme Incompatibility with mixed Light/Dark mode settings

[lolipodass]

I am experiencing an issue with the Zen theme after the latest update, which introduced changes to how dark and light themes are handled.
Currently, I use a light theme on Windows and a dark theme in my browser. Since the update, when the Zen theme is set to dark, content becomes invisible, as shown in the first image.

The "dark theme" I am referring to is the one selected in "edit theme"

The root of the problem appears to be that your code uses --zen-colors-tertiary where --toolbar-bgcolor (which resolves to --dark-light) would be the correct choice.
here is line that have problem

zen-better-findbar/chrome.css

Line 102 in f982bf4

background: color-mix(in hsl, var(--zen-colors-tertiary), transparent 30%) !important;
