How come when we add a mousemove handler to an element, the handler gets fired when we are moving around the whole canvas?

Here's the thing:

If I create a sprite or graphics, and add a mousemove handler for it, then what I expected to happen was that whenever I move my mouse over that element, that handler gets fired, but that's not what's happening, and that handler gets fired when you move the mouse over the entire canvas, why is that?

var el = new PIXI.Graphics();
el.interactive = true;
el.buttonMode = true;
el.beginFill(0x00FFFF, 1);
el.lineStyle(4, 0xFF0000, 1);
el.drawRect(0, 0, 100, 100);
el.endFill();
el
    .on('mousemove', move)
    .on('touchmove', move);
stage.addChild(el)

function move() {
    console.log('mousemove on this element?');
}

You need the hitArea property:

el.hitArea = new PIXI.Rectangle(0, 0, 100, 100);
