Fixes at least some of the failures reported in: jcrist#852 (comment) These were exposed by a bug in 3.14b1 where TypedDict reported incorrect `__annotations__` but correct `__required_keys__`. msgspec would crash in this case. The bug is reproducible on earlier Python versions by manually manipulating attributes on a TypedDict class. It's a pretty marginal bug but I would argue the extension should be robust to this sort of edge case.
