    Height is set to 99.9% because it stops the Samsung browser hiding the UI
    when scrolling down. The Samsung browser behaves as if the user is scrolling
    the whole page when the element being actively scrolled is 100% width and
    height, and absolutely positioned. Kind of clever really.

    Normally this wouldn't be a problem, but when scrolling down on the welcome
    screen and then navigating to the messages screen, the message composer
    will not be pinned to the bottom of the viewport. Instead there will be
    a big gap!

    The only way to get rid of the gap as a user is to manually scroll back to
    the top of the page. I tried programmatically scrolling to the top when
    navigating to the messages screen but this did not work in resetting
    the viewport.

    So here we are, until I find a cleaner fix.
