`paper-input` with `paper-icon-button` as a suffix can't loose focus

[jarrodek]

Description

When you have input that contains paper-icon-button as a suffix it is impossible to use tab to move to the button because paper-input gets focus when button is focused.

Example:

<paper-input label="username">
  <paper-icon-button slot="suffix" icon="clear" alt="clear" title="clear"></paper-icon-button>
</paper-input>

Expected outcome

Should be able to move focus from input to paper button.

Actual outcome

Focus going back to the input element instead of button.
