+# Checks a special case where CSS has both perspective and a transform.
+# In this case, the backface visibility should be computed based on the perspective
+# parent, not the immediate parent.
+# The immediate parent is `rotate-y(-120)`, which is obviously back facing.
+# But perspective transform makes it front-facing (since the frustum side panels are rotated even more).
