Disabled MDButton fires on_press events if pos_hint defined

[cdavidson-project-canary]

Description of the Bug

A MDButton that is disabled will fire on_press events/callbacks if a pos_hint is applied to the button. The on_press events disappear when the pos_hint is removed.

            disabled = True
            )
        screen.add_widget(self.button)

        self.button.bind(on_press=lambda x: self.on_button_press())
