1. Run the scene "ShaderKeywordBugScene"
The scene has one cube with a material that includes a keyword"KEYWORD_OFF", that renders the cube in green. Setting "KEYWORD_ON" would render the cube in red.
2. Press the button "A: Read renderer.shaderMaterial.shaderKeywords".
This will read the shader keywords from the cube's shared material,
and print them on screen. Should print out "shared shaderKeywords: KEYWORD_OFF".
The cube should remain green.
3. Press the button "B: Read renderer.material.shaderKeywords".
This will read the shader keywords from the cube's material,
and print them on screen. Reading the materials properties creates an instance of the material, and all keywords are lost, and printout should be "No shaderKeywords found in material".
Also, the cube has now turned red as it's behaviour defaults to KEYWORD_ON, although no keywords are present.
