TypeError at /admin/wagtailmenus/mainmenu/edit/2/ with Django 5.2 and Wagtail 7.3

This issue relates to #521

I still encounter the same error mentioned in #521 in Wagtail 7.3 and Django 5.2.12. After going back to Wagtail 7.2 it went away.
The release documentation of Wagtail 7.3 states a refactoring of the validation logic in the generic CreateView and EditView, which also affects the snippet EditView that is used here
https://docs.wagtail.org/en/stable/releases/7.3.html#refactored-validation-logic-for-generic-model-createview-and-editview

I have not dived deeper yet into the changes in Wagtail 7.3, but I believe that Wagtail 7.3 is the cause for the error and not Django 6.2 as it was handled in the fix in #521

Me too, just looking at a fix...

Wagtail 7.3 changed its SnippetViewSet URL patterns to use int:pk type converters, so kwargs['pk'] arrives as an int instead of a str. The existing DJANGO_VERSION < (6, 0) guard was added to handle Django 6.0's own auto-conversion, but Wagtail 7.3 made the same routing change independently meaning Django 4.2 + Wagtail 7.3 hits the branch that imports the real unquote(), which then blows up on an integer.

Wagtail 7.2 + Django 5.x passes because Wagtail 7.2 still passes a string pk.
