We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
patternlibrary_override_tags breaks all non-development installations
#8665 added a `patternlibrary_override_tags` tag library to wagtail.admin, which depends on the django-pattern-library package listed in our testing_extras dependencies. However, this tag library will be loaded on all environments that have `wagtail.admin` in their INSTALLED_APPS, so any Wagtail installation that doesn't include testing_extras is currently broken.

As a non-frontend dev, I don't know what this tag library is for, and there's no documentation for me to find out. Deleting it and uninstalling django-pattern-library doesn't break any tests, so it seems to me that it doesn't really belong in the testing dependencies. (If it really is a testing dependency, I'd suggest that moving patternlibrary_override_tags.py into one of the test apps in wagtail/test/ would let it do whatever it's meant to do without breaking non-testing environments.)
