Disable fixed header when keyboard is open in new overlays (iOS)

This is needed because position: fixed doesn't work when keyboard is
open in mobile Safari and the header just stays in the place it was when
the keyboard was opened (covering the content under it). It's the same
fix that was present in the old EditorOverlay.
