A specific repro from  issue 791955  illustrates this problem:

1. Connect to a secure wifi network from the system tray and enter an incorrect password. The 'Join WiFi network' dialog should appear as well as a notification.
2. While the 'Join WiFi network' dialog is still visible, click on the notification.

Observe: The network settings dialog appears over tje 'Join WiFi network' dialog but does not have focus and can not be interactive with, moved, or closed.

This repro has been "fixed" by preventing System WebUI dialogs (SystemWebDialogDelegate) from being opened while the network config dialog is open, however it is still potentially possible for some other combination of modal dialogs to exhibit this behavior.

At this point fixing this is not urgent, but it might be nice to do so at some point.
