[TextInputLayout] wrap the hint text

[bczhc]

When I set the hint text on TextInputLayout, it doesn't wrap the hint text when in wrap_content layout mode, like so:

I don't know if it's the intended result. But I want it expand the view and display the full hint text by default, like:

Currently my workaround is to add the same hint text to the child TextInputEditText and set android:textColorHint to transparent.

I searched and found this on Stackoverflow, but not finding an seemingly elegant way to achieve this. So may
I ask for an extra option or XML attribute if possible, to make the TIL wrap the hint text, or there can be a better way to do this?
