+[PATCH] PyPy3: fix test_issue_18468
+
+When using the small subclass classes to test correctness of split
+results, there are difference between CPython and PyPy3:
+ - CPython returns always the base class (for example str instead
+   of StrSubclass)
+ - PyPy3 returns the same class, so we get an StrSubclass
+
+Based on the test, it looks like the behaviour of PyPy3 is correct,
+but the test works based on CPython.
+
+The fix was to relax the equals type to check that it is a subclass.
