Demo of what happens

STEPS TO REPRODUCE
1. Open Falkon
2. Without close falkon, go to Plasma settings and change theme globaly to a Dark theme (for example Dark Brezze)
3. Go back to falkon

OBSERVED RESULT
Search sugestions bar and tabs keep white. Icons keep dark making them invisible and the rest of UI is black

EXPECTED RESULT
UI should be entire dark, with icons, texts and visible elements in white

I am working on this issue. I have identified a potential fix related to handling runtime palette/theme change events in BrowserWindow. I plan to prepare and submit a merge request by tomorrow.
