Current behavior
I am trying to set attributes such as 'aria-labelledby'/'aria-label' on select box, but the value does not appear. I'm using attributes in templateOptions to set it.

Expected behavior
aria-labelledby should be replaced by the value I provide, it works well in input components.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

ARIA properties are important and should be easy to set, only option I found currently is with attributes in templateOptions, if there is some alternative that would help as well.
