Custom Sprite Kinds

Looking at @KIKIvsIT https://arcade.makecode.com/--skillmap#github:kiki-lee/forest_test/forest.md

How did you get custom Sprite Kinds in the first part of the skill map? Anytime I create:

customts
// Define custom sprite kinds (safe, tiny, and makes toolbox happy)namespace SpriteKind {export const Ship = SpriteKind.create()}
```

and use it in a block:

```blocks

//@highlight

let myShip = sprites.create(img`

..............................

`, SpriteKind.(Ship)

```

It does not work. I have even included // Define custom sprite kinds (safe, tiny, and makes toolbox happy)
namespace SpriteKind {
export const Ship = SpriteKind.create()
}

in the block and I see it referenced correct in the instructions panel, but it does not show up in the drop down and it actually breaks the simulator.
