SUMMARY
When using a dark theme like Breeze Dark, most websites and the developer tools in Falkon do not apply dark mode. This seems to affect all content rendered by the Qt WebEngine. Additionally, the text selection color does not match the accent color set in the Plasma theme.

STEPS TO REPRODUCE
1. Apply a dark Plasma theme (e.g., Breeze Dark) and set a custom accent color.
2. Open a website that supports dark mode detection, such as kde.org or flathub.org.
3. Highlight any text on the website.
4. Open the developer tools (press F12).

OBSERVED RESULT
- Websites remain in light mode.
- The developer tools use a light theme.
- The text selection color does not reflect the Plasma accent color.

EXPECTED RESULT
- Websites should apply dark mode.
- The developer tools should use a dark theme.
- The text selection color should match the Plasma accent color.
