    Bug 688710 - splashscreen shouldn't be always on top on OS X
    
    Activate the "hides on deactivate" behavior for splashscreens,
    torn-off menus, utility windows, tooltips and notifications: when
    another application is brought to the front, these windows are hidden
    so as not to obscure it. This is the expected behavior for
    application-specific floating windows on OS X.
    (cherry picked from commit 0596f5591f36f57b99103914ba03abbed5765e8b)
