Added a case for popup to ignore transitions of focus to BODY in
determining whether to hide. This was causing an error in the following
case: Have a bubble with a button inside of it. Have logic that
disables the button on click, to prevent double-actions. When the
button is clicked, it disables itself, which blurs the button. In IE8,
the focus jumps to the body, thereby destroying the popup even before
the button has finished disabling, causing a "this.renderer_ is null"
exception.
