Bubbling emitter mixin for the view document as described in the [`BubblingEmitter`](module_engine_view_observer_bubblingemittermixin-BubblingEmitter.md) interface.

This function creates a class that inherits from the provided `base` and implements `Emitter` interface. The base class must implement [`Emitter`](module_utils_emittermixin-Emitter.md) interface.

```typescript
class BaseClass extends EmitterMixin() {
	// ...
}

class MyClass extends BubblingEmitterMixin( BaseClass ) {
	// This class derives from `BaseClass` and implements the `BubblingEmitter` interface.
}
```
