Right margin is nearly invisible on default dark theme #706
Description
Xed 3.8.4
Linux Mint 22.2 Cinnamon 6.4.8
If dark theme is enabled (via Preferences -> Theme -> Use dark theme variant (if available)) while using the default Xed theme, the right margin's colors are pretty much identical to the normal background, rendering it unusable. This can be worked around with a custom theme, so I assume it's an issue with the color values used.
