Chrome App web view using Fullscreen & Alwaysontop - google-chrome

Question

I'm working on a Chrome app that opens up using the web view and loads our webpage. I'm trying to make a app that will lock down the web view so when someone is taking a test they can't get out of it or use something else to try and cheat. So the issue I'm having right now is I can't get the Full screen and AlwaysOnTop to work with each other. Is there a way to do this or will these two things not work together and if not is there a hack to get them to work or maybe another direction I need to take. I'm currently running my app with the Chrome Beta since alwaysOnTop doesn't work with the stable version yet. Here is the code in my
main.js
chrome.app.runtime.onLaunched.addListener(function() {
chrome.app.window.create('browser.html', {
state: "fullscreen",
"resizable": false,
'alwaysOnTop': true
},
function(win) {
win.contentWindow.document.addEventListener('keydown', function(e) {
if(e.keyCode == 27){
e.preventDefault();
}
});
win.contentWindow.document.addEventListener('keyup', function(e) {
if(e.keyCode == 27){
e.preventDefault();
}
});
});
});
Any help or some type of direction would be great. I've only been able to get the alwaysontop to work when setting bounds instead but this will display the minimize maximize and exit which kind of defeats the purpose of what I'm trying to do. Thanks in advanced.

you might want to have a look at the "overrideEscFullscreen" permission.
See https://code.google.com/p/chromium/codesearch#chromium/src/chrome/test/data/extensions/platform_apps/prevent_leave_fullscreen_old/manifest.json&q=overrideEscFullscreen&sq=package:chromium&type=cs
manifest.json
{
"name": "Test app for leaving fullscreen rules",
"version": "1",
"app": {
"background": {
"scripts": ["main.js"]
}
},
"permissions": [
"fullscreen", "overrideEscFullscreen"
]
}
main.js
chrome.app.runtime.onLaunched.addListener(function() {
chrome.app.window.create('main.html', {}, function(win) {
// The following key events handler will prevent the default behavior for
// the ESC key, thus will prevent the ESC key to leave fullscreen.
win.contentWindow.document.addEventListener('keydown', function(e) {
e.preventDefault();
});
win.contentWindow.document.addEventListener('keyup', function(e) {
e.preventDefault();
});
});
});
