Jonas Jenwald 32b0e00ba7 Don't dispatch "pageclose" events if a "pageopen" wasn't dispatched for the page (PR 12747 follow-up)
Given that "pageopen" events are not guaranteed to occur, if the page becomes inactive *before* it finishes rendering, we should probably also avoid dispatching a "pageclose" event in that case to avoid confusing/inconsistent state in any event handlers.
