The other option would be checking `Settings.isTabletAndLandscape` in the callback of `SettingsService.navigate` in the `currentPanel` setter. If the app is launched on a tablet, we dispatch the events (moz-app-visually-complete and moz-content-interactive) in the callback when `panelID` equals `wifi`. If it is launched on a phone, we dispatch the events when `panelID` equals `root`.
