Description

[Abe - QA (:Abe_LV)]

Steps to reproduce:
Screen capture: https://testing-1.tinytake.com/sf/MTg2MDgyNF81OTg5NzI1

Steps are taken from: https://bugzilla.mozilla.org/show_bug.cgi?id=1049130#c6

1.) Launch Firefox.
2.) Load the URL: https://www.mozilla.org/
2.) Open the Web Console (option + command + k).
3.) Paste the following JS snippet to trigger a UITour highlight on appMenu.

var event = new CustomEvent('mozUITour', {
    bubbles: true,
    detail: {
        action: 'showHighlight',
        data: {
            target: 'appMenu',
            effect: 'none'
        }
    }
});
document.dispatchEvent(event);

4.) Press F11 to enter to full-screen mode
5.) Verify the highlight is not shifted

Expected results:

The highlight should be centered over the icon even in full-screen mode. 

Actual results:

The highlight shifts when the browser enters to full screen
