_WorldSpacePosLight0 suddenly changes when change camera position or direction

I'm writting a cel shader and all seems fine. But I notcied that sometimes the shadow will be inversed.

I found that the _WorldSpacePosLight0 variable changes suddenly when I change camera position or direction. But I've never change the position or direction of the light.

Who can help me?

Here's a short video to description the problem.

Shader Code: Cel.shader Cel.cginc
