It looks like this is only for the version of this test in System.Resources.Extensions and that the failure is a timeout.

I recall getting feedback to raise the timeout on the original PR, but it looks like I forgot to do it for this version of the test :-/.

Filed a PR to make the two timeouts the same; hopefully this is sufficient to address.
