A quick update debugging this issue. It seems that the root of the problem is that GtkOverlay does not react well when the background widget has its own native window. This feels like a bug in GTK+, but I'm still digging for the cause.

What we know so far is that GtkOverlay creates child windows for all its overlaid widgets and calls gtk_widget_set_parent_window on them. I'm going to try to explore whether or not the overlaid widget windows are just hiding behind the WebView window for some reason.
