title: TextInputLayout counter and margin problem
body: <p>When using <code>TextInputLayout</code> with height set to anything else that <code>wrap_content</code> the counter disappears, and i'd also like to use it with ConstraintLayout, with it's height set to <code>0dp</code>, with that the counter disappears and there's this margin at the top. Can the height of <code>TextInputLayout</code> be set to <code>0dp</code> with visible counter and without this margin at the top? </p>
