Right-click menu's font is wrong

[Kom-Si]

I have set the default system font to be 8 pt.
However when I right-click within a Gedit document the menu is shown in 11 pt. font.
I think it's a bug. Unfortunately while the right-click menu is open in Gedit I cannot make any screenshot - neither of the program window, nor of the desktop itself. I consider that a bug, too.
