Regression

Yes

Shader using UsePass does not recompile when referenced shader is fixed after being broken

-

Steps:

1. Open attached project (ShaderBroken)
2. Open Repro3 scene
> All spheres renders red (correct)
3. On ProjectView, open BrokenSinglePass shader, edit line 47 to make it broken:
return col * float4(1,0,0,1)=;
4. Save file, go back to Unity
> All spheres renders pink (correct)
5. edit line 47 again to fix it:
return col * float4(1,0,0,1);
6. Save file, go back to Unity
> Only the SingleShader sphere is red, UsePass sphere stays pink (wrong)

Expected: both sphere renders red after SingleShader sphere is being fixed
