Good question.
Do you refer to the Node.snapshot()?
The definition of "screen size" is a bit vague on headless, also in relation to window size and view size. I think that a snapshot can in theory be bigger than the screen size, in case multiple screens are used (something we currently don't do).
I believe we can use more input from concrete use cases before we nail down constraints and boundary conditions like this.
