CTRL + Shift selecting selects a single GameObject instead of a range of GameObjects in Hierarchy

Steps to reproduce:

1. Create and open a new project
2. Create 10 different GameObjects in the Hierarchy
3. Select the 1st GameObject
4. Hold Shift and select the 3rd object,
5. Release Shift and hold CTRL, then select the 5th object (to make a gap between the 3rd and the 5th selected GameObjects)
6. Hold Shift + CTRL and select the last item
7. Observe the Hierarchy

Actual results: In Hierarchy, 1-3, then the 5th and the 10th GameObjects are selected separately

Expected results: In Hierarchy, 1-3, then 5-10 GameObjects are selected

Reproducible with versions: 6000.3.0a2, 6000.3.15f1, 6000.4.6f1, 6000.5.0b7, 6000.6.0a4

Not reproducible with versions: 2022.3.75f1, 6000.0.73f1, 6000.3.0a1

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

Notes:

• In the Project window, the selection is correct - expected results are yielded
• In Package Manager, the result is different from the other two - the active selected item does not update to the last selected item, so the previous selection is overwritten by the new selection - all items 1-10 are selected
