1. We were giving precedence of content description over text and this is
what content description is supposed to do - override the text. However,
putting content description on an EditText by mistake would render the
text view not navigable which is pretty much unusable. Now we are giving
precedence to the text and use the content description as a fall back if
text is empty.
