What do you expect to see? That the tunnel is not rendered when it is 
below a waterbody? That has never been the case. Tunnels under water 
have always been rendered the same way they look when under a landmass: 
lighter in color and dashed lines.
Compare the Zeeburgertunnel in Amsterdam (natural=coastline):
<http://www.openstreetmap.org/?mlat=53.5439&mlon=9.9665#map=16/52.3737/4.9748>
Or the Gouwe-Aquaduct (natural=water)
<http://www.openstreetmap.org/?mlat=53.5439&mlon=9.9665#map=19/52.02548/4.66688>
