You have 3 events: first click, second click and 2button-press event generated after second click.

For Gtk2 you have the following sequence of arguments:
(Gtk2::Widget, Gtk2::Gdk::Event::Button) - first click
(Gtk2::Widget, Gtk2::Gdk::Event::Button) - second click
(Gtk2::Widget, Gtk2::Gdk::Event::Button) - 2button-press

But when you use Gtk3:

(Gtk2::Widget, Gtk3::Gdk::EventButton) - first click
(Gtk2::Widget, Gtk3::Gdk::EventButton) - second click
(Gtk2::Widget, Gtk3::Gdk::Event) - 2button-press !!!

I have no idea, why Gtk3::Gdk::Event is used instead of Gtk3::Gdk::EventButton. May be a bug?
Anyway you can bless $event for Gtk3::Gdk::EventButton.
