Hierarchy v2: Going back to "select (multiple) from hierarchy" using undo should not lose selection(s)

Steps to reproduce:

1. Open the attached project and enable hierarchy v2
2. Select single/multiple game objects and drag/drop to a Prefab GO as child(ren)
3. Undo

Actual results: game objects are moved back to where they were, but selection is lost

Expected results: game objects are moved back to where they were, selection is not lost

Reproducible with versions:  6000.5.0a1

Not reproducible with versions: 6000.4.0a3

Tested on (OS): macOS

Notes:

• The issue does not reproduce if the GOs are parented to a non-Prefab GO
