Whenever a `Node` is associated with a `CssStyleHelper`, a suitable shared cache is determined for its use.  This already takes into account the presence of an inline style, and only nodes with the same inline style can share such a cache.  See `Cache#getStyleMap` and specifically this fragment where an additional selector is added for the inline style:

Would it be possible to create a set of tests that verify _all_ the possible combinations of priorities and stylesheets (as well as Application/Scene/Parent/inline/code)?

Also, do you think cssref.html should be updated to clarify the behavior in "Scene, Parent and SubScene Stylesheets" section?
