"On a phone, this would be the expected behaviour."
On a phone, I think it would be better if it opens a new tab (OK), and your focus is on that new tab. I think it's better, because if you're on your phone, and you click on the "twitter button", you can't immediatly realize if your click was ok. Somebody could click two o three time before realizing that webbrowser app already open two or three new tabs.
This is what actually happens with Firefox on Android and even with Explorer on Windows Phone. A new Ubuntu Phone user - coming from that user experience - should expect it.
