Comment 2 for bug 1512901

To test:

Create a new site with 10+ groups and 10+ users

We need to have some users and some groups that have the same id numbers

As admin create a page and share it
- make 2 rows by share with groups and search for the group
- make 1 row with share with users and search for user

Remember the setting - screen grab is good

Save the page then re-edit access

You should see the row for user has changed into a group one where it has selected the group with same id as the user we chose before
