All selected GameObject visibilities/pickabilities are toggled when one of an unselected GameObject is toggled

Steps to reproduce:

1. Create and open a new project
2. Create a few GameObjects in the Hierarchy
3. Select some of the GameObjects in the Hierarchy
4. Click the Visibility button of an unselected GameObject
5. Observe the Hierarchy

Actual results: All selected and the one unselected GameObjects have their visibilities toggled

Expected results: Only the clicked GameObject's visibility is toggled

Reproducible with versions: 6000.5.0a6, 6000.5.2f1, 6000.6.0b2, 6000.7.0a1

Not reproducible with versions: 6000.5.0a5

Can’t test with versions: 6000.0.78f1 (missing new Hierarchy)

Tested on (OS): Windows 11 Pro (25H2)

Notes:

• Only reproduced in the new Hierarchy
