Before this rev., the mobile js tests suite was run on a desktop
like chrome-headless (1366x768). This can be a problem for this
suite which tests mobile behaviors and thus clicks on parts of the
interface that are only visible on small devices (thanks to scss
media queries).
This wasn't really a problem until now, because the test framework
allowed to click on invisible elements. But it's no longer the
case since the introduction of click helpers.
