# Regression test for bug 2034283 (a follow-up to bug 2021812).
# The middle stacking context has a non-zero origin but no transform, which
# triggers the translate-only reference frame insertion path. That reference
# frame must inherit the preserve-3d transform-style, otherwise it becomes
# a flattening boundary inside the preserve-3d hierarchy established by the
# outer reference frame — and the inner rotate-x(60) + translate(0, 0, 200)
# chain gets its z output zeroed, producing the wrong screen position.
