[GLES2][GLSL] Step function does not work properly if edge parameter is a float
Repro steps:
1) Open the project with OpenGLES2 graphics API
2) Notice the cube which is white
3) Change the API to GLCore or DX
4) Notice the cube is now red
Workaround: use float4 instead of float in the step function of shader(See screenshots)

I also have this issue in 5.3.4p4
Device: OnePlus latest OS
Renderer: OpenGLES 3
Workaround: Using OpenGLES 2 as first priority or like the reporter suggests
My workaround:
float4 unity_bug_workaround = float4(sourceColor.r, sourceColor.r, sourceColor.r, sourceColor.r);
float4 unity_bug_workaround_alpha = step(unity_bug_workaround.r, 0.99f);
float alpha = unity_bug_workaround_alpha;
My original code:
float alpha = step(sourceColor.r, 0.99f);
