It is locked - it's just that patterns are locked to the origin (which
is the bottom left by default) and so the pattern moves with the bottom
of the window (making it appear to be scrolling).

I don't remember if "isFlipped" resolves this, but you can always just
explicitly set where the pattern origin phase is (effectively scrolling
as far as the bottom left is concerned, but making it appear fixed for
the top left).
