Shadow Caster Component is not fully updated after performing an Undo action for Casting Source Property

Steps to reproduce:

1. Open the attached project
2. Open the SampleScene
3. Select the Triangle object in the Hierarchy
4. In the Inspector, change the Casting Source property from SpriteRenderer to Shape Editor
5. Observe that the Component view has been updated and some Properties become hidden
6. Perform an Undo action
7. Observe the ShadowCaster 2D component again

Actual results: Casting Source property remains set to Shape Editor, but SpriteRenderer-specific properties reappear

Expected results: ShadowCaster 2D component is fully updated after performing Undo Redo operations

Reproducible with versions: 6000.5.0a8, 6000.6.2f1, 6000.7.0b1, 7000.0.0a1

Not reproducible with versions: 6000.0.84f1, 6000.3.24f1, 6000.5.0a7

Tested on (OS): macOS 26.6.2

Notes:

• Between 6000.5.0a8 and 6000.5.0b11 patches, Undo functionality would not refresh the Component view at all. This behaviour changed from 6000.5.0f1+, where the issue would reproduce as described in the reproduction steps
