Hi,
Thank you for creating useful tool. I got this bug when use Soft Mask
My hierarchy like that.

When SoftMask-Black inside UnityMask-White, everything work properly.
But when I move SoftMask-Black to outsize of UnityMask-White, red image is visible outsize of UnityMask-White

To Reproduce
Steps to reproduce the behavior:

1. Open SampleScene scene on attachment unity project
2. Move SoftMask-Black around for testing
3. See error when move SoftMask-Black outside of UnityMask-White

Environment:

• Version: SoftMaskForUGUI 2.4.0
• Platform: Mac
• Unity version: 2022.3.14f1

I believe that MaskShape stencil was not setup correctly
