Members of groups shared into a project are not easily accessible from the members section

Summary

When sharing a project with a subgroup all inherited members will be added to that project without being visible in the UI.

Steps to reproduce

• Have two users: UserA and UserB
• UserA creates toplevelgroup1 and invites UserB
• UserA creates toplevelgroup1/subgroup1
• UserA creates toplevelgroup2
• UserA creates private toplevelgroup2/project1
• UserA shares toplevelgroup2/project1 with toplevelgroup1/subgroup1

In result UserB will have access to toplevelgroup2/project1 but won't appear in the members list.

graph TD
  root --> toplevelgroup1
  root --> toplevelgroup2
  toplevelgroup1 -.- UserB
  toplevelgroup1 --> subgroup1
  toplevelgroup2 --> project1
  subgroup1 -. shared .-> project1

Problem

UserB is not listed as a member in the /project_members page of toplevelgroup2/project1. UserB is only listed in the Groups tab of the project members page. I want an easy way to see all members at once, regardless of whether they were added directly or via group sharing.
