Build Rules changes not working for git submodules

when using rules:changes, and there is an update to a git submodule within the rules:changes path, gitlab-ci is not running jobs.

The following is an example:

• initial job that triggers downstream pipelines to update git submodules, which should launch a build task: https://gitlab.com/nofusscomputing/projects/ansible/git_configuration/-/pipelines/903907595 MR nofusscomputing/projects/ansible/git_configuration!112 (merged)
• next pipeline ansible-roles (git submodule was updated update): https://gitlab.com/nofusscomputing/projects/ansible/ansible-roles/-/pipelines/903909353
• next pipeline ansible-ee: this job should have triggered a container build as the git submodule is within the rules:changes path: https://gitlab.com/nofusscomputing/projects/ansible/execution_environment/-/pipelines/903911489 MR nofusscomputing/projects/ansible/execution_environment!66 (merged)

This issue needs to be investigated to figure out where the issue is coming from.
