Comment (by afercia):

 Looking back into this, seems to me there's some some parts of the related
 code are pretty old and maybe some overlap has occurred over time, which
 is perfectly understandable in a so large project with lots of legacy ode.

 In `src/js/_enqueues/admin/tags.js`:
 - When submitting the form, `window.validateForm` is called to check
 whether the 'Name' input field is empty.
 - If it's empty, the code in `tags.js` returns false. thus preventing the
 Ajax call and the form submission.

 Actually, this prevents the 'add tag' Ajax action from doing its job.
 Seems everything we need is already there:
 - The Ajax response properly returns success or error messages.
 - `window.wpAjax` parses the response and appends the messages at the top
 of the page.
 - There are already audible messages for screen readers via
 - The form submission is already prevented.

 All the above doesn't run just because of the `return false` in `tags.js`.
 I do realize the current code 'saves' one Ajax request when the field is
 empty but that comes at the cost of missing feedback for users.

 Removing the `return false` does allow the Ajax request to run and return
 the error messages.  Seems to me this would be more inline with the
 purpose of the existing Ajax response.
