Iron-location prevents native hash navigation

[TimvdLippe]

Description

Hashes can be used to point to a section with the corresponding id. E.g. if you go to mydomain.com#foo and there is a <section id="foo"> then the browser automatically scrolls to that section.

Adding app-location (and consecutively iron-location) prevents this navigation from happening.

Expected outcome

Changes to only the hash should not be intercepted.

Actual outcome

Changing the hash does not let the browser scroll to the corresponding section

I cannot reproduce this on the latest firefox. In your jsbin demo, the link works as expected.
