 `term.php` populates `$tag` by calling `get_term()` without a `$taxonomy`.
 If the term ID being edited is still shared, then that `get_term()` call
 will return an `'ambiguous_term_id'` error, which leads to `wp_die()`.

 Per ticket:34988#comment:10, `term.php` assumes there are no shared terms,
 so this might be an invalid report. I can understand if, by this point,
 core considers shared terms to be edge cases at most.

 Technically, the error message ("You attempted to edit an item that
 doesn't exist") is also inaccurate. I can't think of a user-friendly
 description for it, though.
