Notify message doesn't blur out when underlying element is/gets focused

3)
The notify messages should blur out, if a underlying elements are/get focused.
4)
The notify messages impede you when trying to fill in a text box located in the notify area

Steps to reproduce:
Focus some application element located where the notifications usually pop up and wait for a notification. The notification will then not blur so that you won't see what you're writing/doing. The notification even won't blur on new events eg keyboard input.

For example use Firefox in full screen, focus the the search plugin box to enter some key words. (eg using Ctrl-K) Wait for a notification (trigger one) and use the search plugin box. The notify message will then impede you.
