Cancellation Token observability in the Wait method

### Type of issue

Missing information

### Description

Documentation describes how `CancellationToken` is observed when passed to `Wait`, but that seems to mean it is only observed in that initial call.

So, it remains unclear whether the `CancellationToken`, if timed out while a Wait is occurring, will increment the count or throw an exception in the context of the waiting thread/task.
