Please see "Steps to Reproduce". Reproducible: Always Steps to Reproduce: 1.Pin an App Tab with any website (e.g. Facebook.com). 2.Open the new App Tab 3.In the address bar enter any URL that's different from the App Tab's URL (e.g. gizmodo.com) 4.The App Tab's URL gets changed to the new URL (e.g. Gizmodo) Actual Results: The URL of the App Tab becomes the new URL (e.g. Gizmodo.com) Expected Results: I expected the App Tab to remain at the original URL (e.g. Facebook.com). Not sure if this is a bug or a feature, but it's annoying. Maybe make it so that a new tab opens when you type something into the address bar when the current page is an App Tab.
