Can't set a theme

[jst-minor]

Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.
• I have checked that this issue cannot be reproduced on Mozilla Firefox.
• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

Even when I disable DarkReader and Transparent Zen, theme selection won't do what it should to.
The app is installed from AUR.

Expected behavior

The background color should have changed.

Actual behavior

The "Edit Theme" button only allows me to change buttons color. When I try using white theme some parts of interface suddenly turn black.

Steps to reproduce

1. Click "Edit Theme";
2. Try to change color;
   I really don't understand what I did wrong.

I tried to edit theme with open logs, nothing happened. When i switched a few times between console modes I saw this. I don't think this can help.
