eel: Queue resizes on the canvas as elements change visibility
Not queueing resizes may play oddly with the size request caches in GTK+, resulting in gtk_widget_get_preferred_width/height returning 0 even after the canvas was populated. https://bugzilla.gnome.org/show_bug.cgi?id=667831 Taken from: https://git.gnome.org/browse/nautilus/commit/?id=8c77821
