Comment (by boonebgorges):

 @ivankk Thanks for the ticket, and welcome to WordPress Trac!

 It seems to me that this is a problem with the tag selection interface.
 The underlying API allows you to add/remove terms based on term slug or
 ID. It's only when using the tag selector on post.php that you're unable
 to distinguish between duplicate tags.

 One possible way forward is to show the tag slug in cases where there are
 duplicates. So, if you enter 'test' in the scenario described here, you'll
 see:

 {{{
 test
 test (test-1)
 test (test-2)
 test (test-3)
 }}}

 This would require changing the behavior that prevents the selection of
 more than one tag, which may require changing the way that the post
 submission is handled.

 I fear that this suggestion is not very user-friendly, though. Knowing
 that one tag has slug `test-2` and another `test-3` doesn't provide any
 useful information about how to select between them.

 I'm surprised this has never come up before, but I can't find any related
 tickets. @SergeyBiryukov do any existing tickets come to mind? My Google
 skills are failing me.
