    Prevent focus stealing when opening diverted URLs
    
    This patch allows to override current Chrome's behavior, where opening a
    link from an external application (e.g. mail client) causes Chrome's
    window to steal focus.
    It works by introducing a new command line switch
    "--disable-focus-stealing". If this flag is present in a command line
    with URL, existing Chrome window will stay in the backround while
    opening the page.
    
    Fixes #58107 from Chromium's bug tracker.
