For some reason, we postpone clearing the stack of modal sessions until we call
processPostedEvents() again. However, it also means that when we clear the second
modal session, that session keeps running although we just closed its window. The
reason why it isn't stopped is because it wasn't the topmost modal session in the
stack.
This patch fixes the issue by stopping a modal session if any session above in the
stack has been stopped. This makes it less problematic if we don't call
processPostedEvents() in between ending modal sessions.
