When a `trackBy` function is used that accepts a supertype of the iterated array's type, the loop variable would undesirably be inferred as the supertype instead of the array's item type. This commit adds an inferred type parameter to `TrackByFunction` to allow an extra degree of freedom, enabling the loop value to be inferred as the most narrow type. Fixes #40125 PR Close #41995 |
