Steps to reproduce the problem:
chrome.windows.getCurrent or getAll return wrong window width/height/top/left on Windows if window is maximized. For some reason it says window width and height are 16px larger and window top and left are -8px (impossible since the window is maximized).

But... if window is fullscreen, getCurrent or getAll return perfect width/height/top/left. However, outerWidth and outerHeight give wrong values: 16px smaller. And screenY and screenX are +8px (!).

Example:

LINUX
My resolution = 1366x768
Task bar height = 28 (bottom)

Then outerWidth = 1366
     outerHeight = 768 - 28 = 740

chrome.windows.getCurrent({}, function(win) {
    console.log('Expected: ', outerWidth, outerHeight, screenY, screenX);
    console.log('   Given: ', win.width, win.height, win.top, win.left);
});

// --> Expected:  1366 740 0 0
          Given:  1366 740 0 0 (<---- OK!)

Now fullscreen:

// --> Expected:  1366 768 0 0
          Given:  1366 768 0 0 (<---- OK!)

WINDOWS 7
My resolution = 1366x768
Task bar height = 40 (bottom)

Then outerWidth = 1366
     outerHeight = 768 - 40 = 728

chrome.windows.getCurrent({}, function(win) {
    console.log('Expected: ', outerWidth, outerHeight, screenY, screenX);
    console.log('   Given: ', win.width, win.height, win.top, win.left);
});

// --> Expected:  1366 728 0 0
          Given:  1382 744 -8 -8 (<---- FAIL!)

Now fullscreen:

// --> Expected:  1350 752 8 8 (<---- FAIL, WTF?)
          Given:  1366 768 0 0 (<---- OK!)

What is the expected behavior?
chrome.windows.getCurrent should return correct size and position

What went wrong?
chrome.windows.getCurrent returns wrong size and position if maximized. If fullscreen, it returns correct values, but outerWidth, outerHeight, screenX and screenY return wrong values

Did this work before? N/A 

Does this work in other browsers? N/A
