hiding/showing things dependent on screen size not working perfectly when screen size is changed

[jessicasalmon]

There's some issues being caused by the fact that there's no state change forcing a re-render.

• when resizing from small to large screen from the details view, the map remains hidden and on large-small the map is visible when it should be hidden and details view is non visible (probably pushed below map but can't scroll.
• when resizing generally map and map icon don't show/hide correctly
