Duplicate names for objects contained within popovers that are contained within portals.
13 and 14
Operating system version
Description of the issue
I've noticed that copying and pasting a portal can result in duplicate object names on a layout. Specifically, this affects objects that are contained within a popover that is itself contained within a portal row.
Steps to reproduce the problem
In layout mode:
1. Add a portal to a layout.
2. Place a popover button in the portal.
3. Place a named object on the popover body.
4. Select the portal.
5. Duplicate the portal by option-dragging it or copy/paste.
If the original object was named "myObject", then the instance in the duplicate portal should be named "myObject Copy".
Both the original and the duplicate object have the same name.
Of course, we can (and should) rename the duplicate objects appropriately.
