How to change context menu style ?

Hello,

I made a custom theme for Win 11 but it won't show the context menu how I designed it. I enabled the legacy context menu and it works with StartAllBack 3.6 but this version of SAB doesn't show my custom background on details' pane where the Icon is.

Furthermore, I updated to SAB 3.9 and it shows the correct details pane background, bypassing Windows and painting it with the properties I used in my theme msstyle file. But it shows generic dark context menu, not what I have painted in my msstyle.

So here's the summery:
StartAllBack 3.6 -> Correct context Manu but wrong Win 11 default details pane background
StartAllBack 3.9 -> Correct details pane background but wrong Windows drawn context menu (that is coming from somewhere else than msstyle)

I would like to use SAB 3.9 and somehow manipulate Windows to read my msstyle and paint the context menu from it, not just show generic dark context menu which I have no idea where its reading / applying the colors from.

Anybody knows how can I accomplish this ?

Just to reiterate, in case the above explanation is confusing, I want to force Windows 11 to paint the legacy context menu from the properties defined in my msstyle file.

Any help will be greatly appreciated.
