Disable "bounce" effect in NW.js

nwNoScroll.js

var keysToDisable = [37, 38, 39, 40, 33, 34, 35, 36];

function preventDefault(e) {
	e = e || window.event;
	if (e.preventDefault) {
		e.preventDefault();
	}
	e.returnValue = false;  
}

function keydown(e) {
    for (i = 0; i < keysToDisable.length; i++) {
        if (e.keyCode === keysToDisable[i]) {
            preventDefault(e);
            return;
        }
    }
}

function wheel(e) {
	preventDefault(e);
}

function noScroll() {
	window.onmousewheel = document.onmousewheel = wheel;
	document.onkeydown = keydown;
}

noScroll();

It seems to only affect 0.12-alpha3 version of nwjs. The CSS trick described in #3109 is working fine with the latest version (0.12.2) and does not block the scroll on the entire page.
