Thanks @Globulopolis for the feedback we didn't notice that one.

It is caused by this: https://github.com/piwik/piwik/blob/2.13.0-rc3/plugins/CoreHome/javascripts/popover.js#L47

This will call https://github.com/piwik/piwik/blob/2.13.0-rc3/plugins/CoreHome/javascripts/broadcast.js#L381 which causes the page to scroll to top here: https://github.com/piwik/piwik/blob/2.13.0-rc3/libs/jquery/jquery.history.js#L14

This won't be an easy fix. We could store the current scroll position and restore it afterwards but then it the page will jump. According to eg this blog post we could use the actual history API: http://lea.verou.me/2011/05/change-url-hash-without-page-jump/ . The history plugin that we use is outdated and no longer maintained since beginning 2012 : http://tkyk.github.io/jquery-history-plugin/ . Maybe we should consider using another history plugin. The author of this plugin recommends the following plugin: https://github.com/cowboy/jquery-hashchange

@sgiehl any thoughts here maybe?

I think this can be solved easily w/ a proxy in between broadcast & jquery's history plugin. I'll work on a PoC.

Fixed the issue in a PR (#7869) w/o a new library. Instead of using jquery's history plugin, we can just use angular's $location object. Works pretty well as far as I can tell.
