Allow access to a wizard's scene

When creating a Wizard, it would be nice to be able to apply a custom css to its Scene, so that all Panes that are added into the Wizard can inherit it.
In my case it was something as simple as:

#!css

.root {
    -fx-base: rgba(60, 63, 65, 255);
}

to have a "dark" look and feel.
Without access to the Scene one would have to customize style for each Pane and for .dialog-pane > .button-bar and .dialog-pane:header and many other details.
I would add that that even if I tried this last option, it didn't seem to work as expected: in my example the text color for labels was modified to white, while the background color wasn't correctly derived from the customized "-fx-base" and remained of a light color derived from the default "-fx-base" (that is #ececec"), thus creating the effect of "light text on light background".
What I propose is to allow access to the wizard's Scene (or alternatively to the list of stylesheets).

Any update here? Or is there a workaround for styling the wizards dialog?
