Context menu fallback for custom Windows theme?

Hi, thank you for making a CSS for titlebar buttons fallback.

There's a similar case where Firefox uses high-contrast menu when custom Windows theme is set. Can you make another style that falls back to using Proton context menu style?

Proton style vs high-contrast style:

I can't really test this but there's a old gist I cooked up which is supposed to do that. You could test if that works.

Nope, it's all white. This also happens when using the default Windows theme + Firefox dark theme.
