Edit-button in summary does not navigate to correct item in repeating group

### Description of the bug

The summary component (Summary2) does not navigate to the correct item when the "Edit"-button is clicked. Instead of jumping to the specific item within the repeating group that needs editing, it only navigates to the overview page displaying all items in the repeating group.

The repeating group has edit: "openByDefault": "first". If I remove this it manages to jump to the correct item.

### Additional Information

_No response_

Start by reproducing the Summary2 Edit-button behavior with a repeating group whose edit setting is openByDefault: "first", using the linked reproduction. Trace how the button selects the item and how the repeating group opens it; done means the button navigates to the specific item rather than the overview, while preserving the behavior when openByDefault is removed.
