[BUG] The light theme does not apply

[IngvarListard]

When the system automatically switches to the light theme, this widget does not update its theme accordingly. The buttons and title remain white.
When I change the theme between light and dark myself from the settings, everything works correctly.

OS: ubuntu 26.04
KDE: 6.6.6
KDE Frameworks: 6.24

Hi,
Only the Application Title Bar doesn't change?
Could you show full panel?
Is there same problem when you are changing the theme from the Settings?
