@artl93 I would like to backport this simple bug fix to 10 RC2. To tell the long story short we have removed the default timeout in Preview 7 and this PR is adding it back. |

Customer Impact
The preview 7 and later releases of System.CommandLine included an API change that resulted in default cancellation behaviors for System.CommandLine-based applications changing. in preview6 and earlier, the library was configured so that Ctrl+C would cause a
System.OperationCanceledExceptionto be thrown, giving user code a simple hook to catch and react to that. Preview 7 and later dropped this behavior unintentionally, causing some users to report that their cleanup/cancellation code was no longer being triggered.How was it found
An external user, @mpatkisson, discovered the issue, did detailed investigation and analysis in #2671, and then contributed a fix in #2672.
Risk
Low. The existing cancellation mechanisms in use are under test, but we did not have a test that covers the documented 2s cancellation default behavior, to ensure we didn't regress it. This has been manually tested, and we will shortly add a test to the repo to prevent regressions.
