extra estate taken by shinyalert in body at start-up

[dylancis]

when using shinyalert(id, click.hide = TRUE, auto.close.after = NULL) in dashboadBody, eveif it hidden by default, it does take some estate of the body for nothing.
In server.ui I have used hideshinyalert(session, id) to overcome this but you see the show/hide effect once you open the app.

Anyway we could by default hide it in ui.R?
Thanks, Dylan
