Double-click issue affecting window location by appending #

I've noticed that double-clicking on a color picker to select a color also seems to affect the browser's address bar, specifically, by appending a # character. This can actually be re-created on the project homepage at [http://automattic.github.io/Iris/](http://automattic.github.io/Iris/).

This causes serious problems for single page apps. Right now it makes Iris unsuitable for the BackboneJS app I'm working on. Can anything be done?

Reproduce the double-click behavior on the Iris project homepage and inspect the color picker’s event handling and browser URL changes. Done means selecting a color with a double-click no longer appends a “#” to the address bar, while color selection still works.
