-    Ensure that openapi model descriptions that originate from Pydantic docstrings always truncate the docstring to text
-    that falls before the formfeed (\f) character. This feature was introduced in (https://github.com/tiangolo/fastapi/pull/3032).
-    When originally introduced, there was a possibility that the truncation may be ignored depending on the order in which
-    the models got processed. This created non-deterministic errors, since Pydantic model processing uses unordered sets
-    and model ordering may differ from one invocation to the next.
-    This test verifies that (\f) escape of docstrings works in all possible orderings of our two Pydantic model classes.
+    Regression test for bug fixed by https://github.com/fastapi/fastapi/pull/6039.

+    Test `get_model_definitions` with models passed in different order.
