There are 2 selectors in caspian.css like this:
*:disabled > * > .label
:disabled > * > .scroll-bar

As any parent can be disabled and can possibly have label/scroll-bar in his subtree, all parents will have to create their StyleHelpers, even if there are no labels/scroll-bars under them.

Question is, if these selectors could be avoided or otherwise StyleManager/Node/Parent code should be optimized.
