But what would you expect to get? When more than one-earth's worth is
shown on the screen, the concept of bounds becomes a bit meaningless;
a bounds bigger than the world makes no sense yet that might be the
thing that is wanted.
You can write code to detect this situation and deal with how you
wish ; I do not think Google can do that for you because different
folk will want different results.
