Tooltips for {{paper-input}}

Hi there!

I'm trying to implement a tooltip feature for the paper-input component. I'm not able to get it to render when placed inside of the `label` tag. When I move it out of the `label` tag it renders without any problems.

Is there any reason for this? I've tried playing around with various css properties without any success.


```hbs
{{#if label}}

{{label}}

{{#if tooltip}}
{{#paper-icon "info"}}
{{#paper-tooltip position="right"}}{{tooltip}}{{/paper-tooltip}}
{{/paper-icon}}
{{/if}}

{{/if}}
```

Cheers!
