ubuntu-mate welcome opens freenode webpage link in itself

To reproduce open ubuntu-mate-welcome and then click on chat then click the green link for freenode. ubuntu-mate welcome will open the webpage for freenode in intself and not a normal browser.

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

I expected this link to freenode to work like the links in the introductoin to microsoft or ubuntu or about desktop enviornments. Instead ubuntu-mate welcome tries to open this link in itself amd then results in being unbale to navigate to the other pages of ubuntu-mate welcome but clicks on the parts of the freenode website.
