## Summary Fixes a bug observed by @AlexWaygood where `C[Any] <: C[object]` should hold for a class that is covariant in its type parameter (and similar subtyping relations involving dynamic types for other variance configurations). ## Test Plan New and 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.
