Can I get a review? 
https://github.com/python/cpython/pull/29202

Seems like a simple mistake given the original description of this issue:

> 1. the inner task is completed and the outer task will receive the result – transport and protocol in this case
> 2. The inner task is cancelled and no connection was established

The try/except blocks clearly add a 3rd condition, where the inner task is completed and a TimeoutError is raised without returning the result.
