Broken pagination URL in admin projects list with namespace filter on

When I go to /admin/projects, filter by namespace and try to use pagination, it leads to 404 page.

For example, '2' has the URL /admin/projects/5?page=2 but it should be /admin/projects?namespace_id=5&page=2.

The issue is still present in 8.8.2.

Started GET "/admin/projects/22?name=&page=2&sort=&utf8=%E2%9C%93&visibility_levels%5B%5D=10" for 127.0.0.1 at 2016-06-01 09:57:38 +0200
Processing by Admin::ProjectsController#show as HTML
Parameters: {"name"=>"", "page"=>"2", "sort"=>"", "utf8"=>"✓", "visibility_levels"=>["10"], "namespace_id"=>"22"}
Filter chain halted as :project rendered or redirected
Completed 404 Not Found in 42ms (Views: 0.7ms | ActiveRecord: 3.3ms)
