Because setClassNames can be expensive, we only want to do it if we have to.
The component lifecycle is designed for setting lots of properties before
adding a component to its parent. There is a call to setClassNames in
addedToParent for that reason, so other calls to set the className shouldn't
bother to do all of that work.
To me, it is far more worrisome that the parent property is undefined. We need
to understand why that is the case. Lots of other things could break due to
that. If you look at the component's element and check the element's
parentNode, is it defined? If so, then the parent getter should not be
returning undefined. Step into the parent getter and try to see why.

Alex,
I did more experiments to that, but not sure whether it's ok. In those two
places I had parent - undefined [1] (UIBase) [2] (ClassSelectorList). As
you can see I commented out those condition and everything started to work
properly.
The question is - Why those condition even there here ? Did you or Carlos
had and scenario where something was crashing without it ?
