I disagree here, the "transparent-bg-hint" should only be set if the engine is drawing directly on the canvas. This is not the case if Gecko fills in the background.

I am not sure I understood everything from comment #41 :-)

However, I do not see any advantage in registering the style property on GtkWidget (so that it exists on all widgets). AFAIK a style property is only needed for GtkEntry.
