The Group console doesn't work in AEM Communities deployed on an application server

When deploying AEM to an application server with a different context path for publish instances versus author instances, then the Group management console fails to autoscroll.

Reproducible steps:

1.  Set up Apache Tomcat 8.5.x
   
   
2. Install an AEM 6.3.2.1 author instance and AEM publish instance via war file deploy under /aemauthor and /aempublish contexts (respectively).
   
   
3. Set up the AEM Tunnel service with the proper context /aempublish configured (in the OSGi configuration): https://docs.adobe.com/docs/en/aem/6-1/administer/communities/users.html#Tunnel%20Service
   
   a. Go to /system/console/configMgr/com.adobe.cq.social.user.impl.transport.HttpToPublisher
   b. Set context path to /aempublish
   
   
4. Go to /aemauthor/communites/groups.html/content and see that autoscrolling isn't working, it gives a 403 error.

The same problem occurs for /aemauthor/communites/users.html as well.

This problem only occurs when you have a context configured other than root /.
