Compile time error when EventEmitter type contains a period (static analysis error?)

[snaptopixel]

Stencil version:

 @stencil/[email protected]<version>

Current behavior:
I'm using ambient type declarations with namespaces like myComponent.SomeType in my stencil lib. Works great, but the second I do this: EventEmitter<myComponent.SomeType> I get a cryptic error when compiling:

[ ERROR ]  /path/to/my-component.tsx
           Cannot read property 'toString' of undefined

The problem goes away when there is no period, if I do something like:

type SomeType = myComponent.SomeType;
// Omitted code
@Event() foo: EventEmitter<SomeType>;

Expected behavior:
If it is valid TypeScript it works with Stencil
