+# This test ensures that we flatten the trasformations (i.e. zero out Z coordinates)
+# at the boundaries of preserve-3d hierarchies.
+# If the stacking context isn't flattened at the preserve-3d boundary here,
+# it's non-zero Z component starts affecting the screen space position
+# due to the "rotate-x" transform at the top level.
