Re: [PATCH v5 0/1] MR5861: mshtml: Implement visibilitychange event.

[Jacek Caban (＠jacek)]

Note that minimizing a window is just one case where this event should fire, but there are many others. In regular browsers, switching tabs is probably the most common source of the event. To support that, we would need to detect real visibility changes of the document, not just window minimization.

That said, we do not need a complete solution right away, but since even the limited support already requires awkward hooks, this does not look very appealing. What exactly is it fixing? Do you have an actual application that needs it? And what is the observable behavior difference between this MR and just a stub?
