+        This tests that a placeholder Node can be matched to a Node with

+        while the pattern we want to match looks like this:

+            call_method    dequantize                                                  (x,)                      {}

+        Here, we want to be able to match the original graph's
+        `call_function.add` Node with the pattern graph's
+        `plaeholder.x` Node.
