Menu bar doesn't follow dark theme

[korakios]

Hi,
I noticed that on flatpak version , the menu bar doesn't change the color when changing the theme
It looks like this :

If not possible ,maybe an option to remove the menu bar since there is already an option to go to settings from the 3 dots ?
I know it's just a cosmetic issue but it's a bit annoying on dark environment

Edit : on KDE Neon 5.26 using X11
