Comment (by mrahmadawais):

 @westonruter I just tested the latest patch and here's what I think

 - In example plugin, the error being reported is wrong, it should read
 `You must supply a Navigation Label` instead of the `title` which begs the
 question of building a custom notification renderer which could get back
 the fieldname with WP_Error instance.
 - CSS Spacing issues are evident almost everywhere with the error
 notification. I can contribute on that part but probably it has more to do
 with how notifications are being rendered. Check the images attached
 below.
 - Would it be better if we can designate a certain area for notifications
 at the top so that folks building custom controls won't mess up the
 notifications

 Check the red line to visually differentiate the odd spacing issues.
