Be more explicit about necessity of `perspective()` argument about interactive-examples

I don't think that's the key point of this example. Live examples almost never provide reproducible code—rather, they hold all other variables constant so you can observe the effect of this one feature in a sufficiently complicated context.

That said, we'll leave it open so (1) the invalid case can be fixed (2) maybe someone has a different opinion.

Here's a gif demonstrating that other properties are required for the effect but they are not made clear in the article:
