Can't nest a paper-icon button inside a gold-phone-input

[Sambender9]

I want to be able to nest a paper-icon-button inside a gold-phone-input as to be able to clear out the input. I have an 'X' btn that calls a function that clears out the input when clicked.

Actual outcome The paper-icon-button does not show.

Expected outcome The paper-icon-button would show just as it does when nesting it inside a paper-input

Steps to reproduce

1. Create a gold-phone-input
2. Nest a paper-icon-button
3. Open a browser

I think the solution here would be to port the prefix/suffix code from paper-input, and add them here as well. Then you could distribute a paper-icon-button in one of those slots.

Would you be interested in sending a PR for that
