Menu is not scrollable on mobile phones
When the menu's height is greater than the screen height, we can't scroll to reach the bottom of the menu. Reproducible by opening all the banks account in the menu and using the "Nexus5X" responsive mode in Chrome, and trying to scroll with the little dot (which symbolizes the touch) instead of the mousewheel.
