So I've been looking into this. This is an interesting combination of different states. The [x] is not actually (explicitly) closing the first open popup. This is just how one perceives it. The issue has two components:

- The first open popup in that screencast happens to be a popup with the removeOnDismissal property set to true.
- The second popup is a persistent popup with an [x] button.

These latter type of popups are supposed to lose their persistent status and become dismissed once the [x] was clicked. The implementation looks like this[0]. This is where things are starting to go wrong. We can see that the _dismiss method only considers the firstChild of the panel, even though the [x] could have been clicked on a different popupnotification. As a result, the second notification does not lose its persistent status and will remain shown. The firstChild, on the other hand, gets dismissed (that just seems to be how the [x] works, all non-persistent popups get hidden). But since it has removeOnDismissal, it automatically removes itself when hidden. And so it seems that the [x] only removes the first popup when in fact it tries to hide both.

My suggested solution is to correctly apply the persistent = false and keep the remaining behavior as it is. This basically leads to both popups being correctly hidden and the restart popup being removed. Looking at bug 1315236 comment 19, we will soon remove the removeOnDismissal property from the restart popups anyway.
