When the user gives the combo box focus, it only reads aloud the internal combo box help text ("You are in a combo box..." etc). It should additionally behave as a regular text input, and read the placeholder, the form label, and the description text to the left. This may be a case of aria props not being correctly transferred to the input inside of the combo box.

I think my VO was acting up. Everything gets read correctly except for the placeholder, so I've updated the issue title to reflect that.
