Missing project permissions from shared group permissions on new project

Summary

When sharing groups with groups, newly created projects in nested "project" group are not accessible to users in the "teams" group.

Steps to reproduce

Have a group of users (all are "Maintainer" level in this group): /teams/my-group

Have a group "/projects" and invite above group "/teams/my-group" to it.

After inviting the group, all members of the group have access to projects within /projects and below, also to /projects/nested/groups/mylib. Fine. Now create a new project /projects/nested/groups/anotherlib.

Expected behavior: The users from /teams/my-group can also access /projects/nested/groups/anotherlib Observed behavior: The users from /teams/my-group get 404 when accessing /projects/nested/groups/anotherlib

Workaround: Revoke access to /projects for group /teams/my-group and re-invite the group. Now all members of /teams/my-group have access also to /projects/nested/groups/anotherlib
