There was a problem hiding this comment.
This guard condition correctly prevents the error, but there's no test coverage for this edge case. Consider adding a test that verifies setViewport behaves correctly when called on a view model with all lines hidden (getViewLineCount() === 0), similar to the existing tests in viewModelImpl.test.ts for hidden areas.
