GtkSwitch is unusable when added to primary toolbar.

If a GtkSwitch widget is added to a primary toolbar, it becomes unusable with left click. Right click and keyboard control works fine but left click starts to drag the toolbar and as a result the whole window. This problem does not exist of any other widget I tried. Also, it goes away if I don't use a Gtk3 theme.
So the problem lies with toolbar's (with 'primary-toolbar' style property) drag taking precedence over Gtk.Switch drag.
