How to force dark mode in [google] Lookup/search (Ctrl-L)

Hello,

Recently The Lookup feature in calibre reader is not using the default dark theme of chrome.

This used to work previously, and I have no Idea how to change it back

Additional Info:

OS Fedora KDE Linux

Calibre Version 7.13

Chrome Theme QT - System (Although I tried all possible combinations with no luck)

Any help is appreciated

Cheers
