fitToBox doesn't take viewport offset into account

[samevision]

Describe the bug

I set the viewport for controls like this:

controls.setViewport(-camera.view.offsetX, -camera.view.offsetY, camera.view.fullWidth, camera.view.fullHeight)

But if I call fitToBox() it still fits to the whole canvas instead of my defined viewport.

How can I fix this?
