In #41995 the type of `TrackByFunction` was changed such that the declaration of a `trackBy` function did not cause the item type to be widened to the `trackBy`'s item type, which may be a supertype of the iterated type. This has introduced situations where the template type checker is now reporting errors for cases where a `trackBy` function is no longer assignable to `TrackByFunction`. This commit fixes the error by also including the item type `T` in addition to the constrained type parameter `U`, allowing TypeScript to infer an appropriate `T`. Fixes #42609 PR Close #42692 |
