Returns the active scope(s) for a given control by looking up the hierarchy.

The lookup navigates the DOM hierarchy if it's available. Otherwise if controls aren't rendered yet,
it navigates the control hierarchy. By navigating the control hierarchy, inner-html elements
with the respective scope classes can't get recognized as the Custom Style Class API does only for
root elements.
