Found while building both mypy-extensions 1.0.0 and 1.1.0 on NixOS.
Building against python 3.14.0a6. Python 3.14 is expected to release 2025-10-07, so there is still time to fix this.
I understand python 3.14 is currently an alpha, but it imo it makes sense to report these things as early as they are found.

Commencez par reproduire l’échec dans tests/testextensions.py avec Python 3.14.0a6, en vous concentrant sur TypedDictTests.test_py36_class_syntax_usage et les annotations de LabelPoint2D présentées dans le rapport. Comparez les annotations observées avec le mappage attendu du test et vérifiez que le test réussit sans casser les 11 autres tests.
