Comment 1 for bug 1337284

I don’t think this issue should be worked around in the browser app. It’s an issue in the shell, and it should be fixed there. It has existed since the very beginning, and it affects all applications that react to orientation changes and expose some sort of functionality through the bottom edge.

Note that webbrowser-app uses the standard MainView component from the UITK, which handles orientation changes under the hood, so I don’t think we can hack it to force portrait mode. Besides, even if we could, it wouldn’t make sense to break the UX (starting in portrait mode while in landscape orientation is unexpected) to make the tests more reliable.

What about the orientation sensor’s sensitivity? It looks like this is a relatively recent regression, couldn’t it be fixed/improved there?

Finally, have we considered a setup where test devices are standing upright, to prevent this from happening at all?
