When ColorShader (debug shader for preview) is selected, and an assembly reload is performed, texture properties can be infinitely generated. IS this a symptom of a greater issue in the preview generator?

Repro Steps:
- Ensure you have a folder "DebugOuput" in the root of Assets
- If you have just created this folder then deselect Unity editor and reselect to force asset database refresh
- Create a new ShaderGraph and open it
- Add a Sample Texture 2D node in the Shader Graph and save it
- Select ColorShader in DebugOutput
- Edit any script in the project/package to force an assembly reload
- Notice in inspector infinite texture properties are being added to the ColorShader
- Continues until deselecting ColorShader and selecting revert
