Erroneous text about discards suppressing task exceptions

Type of issue

Other (describe below)

Description

In the A standalone discard section, the example about assigning a Task.Run result to a discard says that "Assigning the task has the effect of suppressing the exception that the operation throws as it is about to complete", but this is not true, as the next note suggests ("Without a debugger attached, the exception is silently ignored in both cases"), the only thing the discard suppresses is the compiler warning.

Thanks @Trisibo

I've added this to our backlog.

Thanks @BillWagner. I believe that the new ending sentence is also incorrect, though ("You want to discard the Task, and propagate any errors generated from that asynchronous operation to callers"): as far as I know, the exception would not be propagated to the callers, but it would be onobserved, right? The original sentence ("You want to discard the Task, and ignore any errors generated from that asynchronous operation") seemed better to me.
