Steps to reproduce:
1.Open a page with VE
2.Go to Cite>Website
3.Insert a URL such as "http://www.facebook.com"
4.Click on "Insert"
5.As soon as the context menu appears, click on the URL you just added
It asks user whether to leave the page and attempts to open the URL in the same page instead of opening it in a new tab.
It happens only the first time, if you try clicking on the URL next time from context menu, it opens it on a new tab straight.
