Discussion:
The main purpose of affine_on is to make sure work
resumes on a specific execution context. The scheduling operation
may take some time and work may be cancelled in the meantime. If

context. Thus, the stop token from the receiver's environment should
only be forwarded when connecting the sender but not
to the scheduling operation.
