Description

In the config shown 'functional-test-component-2' and 'functional-test-component-3' have the same (single) component instance. If you then stop 'functional-test-component-2' you'll be rendering 'functional-test-component-3' non-functional because it's component gets stopped.

Only decent solution that occurs to be for now is to disable use of inherited component elements.
