Separating variables by commas makesPropertyAttributes appear between all variables in Unity Editor.

If I use:

Code (CSharp):

1. [Header("Renderers")]
2. [Space(10)]
3.  
4. public Renderer neonRenderer, neonglowRenderer, circlebg1, circlebg2;

Those property attributes appear between all the variables, instead of only above the first one.
How do I fix that?
