Update Permalink/Slug Previews in Admin

Lýsing

In WordPress, a page’s parent or the categories of a post typically influence the final permalink/slug URI.

When editing a post or page in the WordPress admin backend and changing any of these, the preceeding URI parts before the slug below the title input don’t get automatically updated though – pretty confusing.

This simple extension automatically reloads/refreshes the permalink preview URIs when having selected different page parents or post categories.
