## Summary We had tests for this already, but they used generic classes that were bivariant in their type parameter, and so this case wasn't captured. closes https://github.com/astral-sh/ty/issues/1702 ## Test Plan Updated Markdown tests
Markdown files within the mdtest/ subdirectory are tests of type inference and type checking;
executed by the tests/mdtest.rs integration test.
See crates/ty_test/README.md for documentation of this test format.
