Do not autofocus text fields on page load on mobile devices. This is currently broken in many mobile browsers:

- iOS Safari opens the keyboard and auto-scrolls on the first tap anywhere on the screen triggering the click at an unexpected place. That makes it impossible to follow links or press buttons.
- Chrome on iOS opens the keyboard on load and may scroll the focused field off screen.
- The Android 4.4 browser only highlights the field, the user has to tap it to open the keyboard and type.
