'backrefs' module has no attribute 'compile' after upgrade to 9.6.6 #8056
Description
Context
Noticed originally in CI because the job succeeded despite failing and deployed a broken page (my fault on the CI fail ;)): https://github.com/rocky-linux/docs.rockylinux.org/actions/runs/13619078285/job/38065965051#step:4:657
Bug description
When attempting to build even a completely minimal reproducer, builds fail under multiple conditions with the following:
ERROR - Error building page 'index.md': module 'backrefs' has no attribute 'compile'
Traceback (most recent call last):
