Comment (by delawski):

 What about a case when user is modifying some field that is 'below the
 fold' (the Customizer pane has been scrolled down) and a notification is
 displayed? Should the pane scroll back automatically to the very top in
 order to show the error message? In such case the control that caused the
 error would get out of the screen and the message would have no 'context'.

 Even in case of editing field that is above the fold, new notification
 would push the whole content down. It could be confusing to the user.

 What about having the notification area fixed to the bottom border of the
 header-action bar? It would be displayed over the content and visible no
 matter how 'far' the user has scrolled the pane. In case the pane is in
 its initial position (has not been scrolled), the content area would be
 pushed down to make space for the notifications. It would work pretty much
 the same as now the header-actions bar does.

 Due to limited screen real-estate the notification area wouldn't be fixed
 for mobile/small screens.
