select box not showing properly

Hi:
I updated the core contact form component to show a dropdown list of items for append on the contact information form.
The contact page show the other fields correctly aside of the dropdown list.
The html code is correct but I don't see the select box icon.

Hi

In select box there is a value size="50", this should be changed to size="1".
