How can I prevent input processing while an element is focused?

[Vaughan]

I have a textbox overlay and I want to prevent any key input from working (within Phaser) while this is active. The game is not set to pause when it loses focus. Is there a handler I can abuse or something?

Phaser.Input.disabled will do it, a la:

game.input.disabled = true;
