    Summary: Task dropped in wrong thread when aborting `LocalSet` task

    Details: When aborting a task with `JoinHandle::abort`, the future is dropped in the thread calling abort if the task is not currently being executed. This is incorrect for tasks spawned on a `LocalSet`. This can easily result in race conditions as many projects use `Rc` or `RefCell` in their Tokio tasks for better performance. See [tokio#3929][issue] for more details. [issue]: https://github.com/tokio-rs/tokio/issues/3929
