Comment:

 One possible way to fix this Safari+VoiceOver issue is appending a no-
 break space character `\u00A0` to a repeated string, this way the new
 message will be "different" and VoiceOver will announce it. I've tried
 also with other invisible characters, but the no-break space looked
 "safer" to me. Any thoughts welcome.

 The post Tags meta box is one place where testing this is very easy:
 - without the patch applied, click on "Choose from the most used tags"
 - then click on a few tags: VoiceOver will announce "Term added." just the
 first time
 - same when removing tags, clicking on the "X" close to the tag names

 With the patch applied:
 - repeat the steps above
 - VoiceOver will announce "Term added." and "Term removed." each time a
 tag gets added or removed

 Would greatly appreciate any thoughts on the addition of the `\u00A0`
 character. If no objections, I'd like to propose to consider this for the
 4.7.5 release, as it's a long standing, annoying, bug for VoiceOver users.
