JS datepicker resets url on angularjs pages

The javascript datepicker resets the current document url when selecting a date if it is used in the angularjs context. This is most likely caused due to the dates being hyperlinks which href-attributes are set to "#":

<a class="ui-state-default" href="#">27</a>

Steps to reproduce:
1. Add a crm-ui-datepicker to an angularjs-page
2. Select a date
3. The url gets reset (i.e. from "/civicrm/a/#/campaign/41/view" to "/civicrm/a/#"

This also leads to dialogs acting weird, like being mispositioned or scrolled to the top, when used in combination with a datepicker.

I can provide an example page if necessary.
