In my Drupal 8 site (using the Seven theme), the primary tabs navigation are displaying differently for different roles. See screenshots below.
It would appear that for the limited Editor role, it's showing the tabs in some sort of space saving '...' dropdown menu (all the other tabs are hidden underneath the '...').
The browser windows are the same size and there is clearly plenty of room for all of the tabs as you can see in the Admin view.
What's going on here? How can I make the tabs on the Editor role look like they do on the Admin role?
