Well in reality these active  UI elements fail SC 1.1.1 . They are non text elements that have no text equivalents. How is a non-visual user supposed to understand what they  are? So the UI elements need to comply with SC 1.1.1 first, then evaluated for SC 1.4.3 (contrast) and SC 2.4.7 (visual focus indicator). 
No problem with WCAG 2 there.
But I do not understand why "inactive controls that are not visible to anyone" figure in the text of SC 1.4.3 under exceptions. If it is not visible then how does contrast matter?
My contention is that SC 1.4.3 and SC 2.4.7  should be elevated to  Level A status. I see quite a few transgressions of these SC. There are no readily available and workable fixes  via features of the browser / assistive technology for these two SC. In fact some users who do not use AT may encounter these issues. The fixes have to be done by Web content developers.  I'll be happy  to learn if this is incorrect.
