Material Type Toggle Reverts when changing selection

Expected Behavior * The Thin material type selection should persist across selection changes.

• Material state should remain stable and consistently reflect the user’s last saved or applied settings.
• Switching away from the material should not trigger a reset of its type or other parameters.

Actual Behavior * The Material Type toggle automatically reverts from Thin back to Standard after selecting another object or material.

• User changes appear to be ignored or overwritten by the material system on refresh.
• This prevents users from reliably using the Thin material mode for fabric materials and creates confusion about whether the property was applied.

1. Select any fabric material in the scene.
2. Open its Material Properties.
3. Change the Material Type toggle from Standard to Thin.
4. Switch to any other material or deselect the object.
5. Re-select the original fabric material and reopen its Material Properties.
