[3.15] gh-141510 Document and test frozendict class matching behaviour (GH-150799) (#151701) gh-141510 Document and test frozendict class matching behaviour (GH-150799) Frozendict has `_Py_TPFLAGS_MATCH_SELF` set so works correctly with the single-arg class matching. However it isn't documented in the list of classes this works with and it isn't tested. The test is some way below the other similar tests but anything else would need a large renumbering.
