Explanation

• What is the expected behavior?
  It should verify if document.activeElement is an element related to tagify before calling blur()

• What is happening instead?
  The blur() method is called on document.activeElement regardless of whether the active element is part of Tagify. This leads to a scenario where any focused element will lose focus, disrupting user interactions outside of the Tagify context.

tagify/src/tagify.js

Line 1011 in 3ecfbc2

document.activeElement.blur() // exit possible edit-mode

I'm unsure what this line is meant to do.
I guess it's here to exit edit-mode on tags, as the tagify input should loose focus naturally when it has the readonly/disabled attribute.
